Skylights, I think you have done an excellent job of addressing the points on that list. One of the problems I think we have is that it is very hard to see what our behaviour looks like to other types based on their functions and what those behaviours would then indicate to them. Therefore it's hard to explain the differences if we don't know quite where they lie or what is preventing them from being understood accurately. In every case here though, I would agree with the possibilities you have presented.
Regarding number 6, I've thought of one context where I do this. There is something in me that really hates making decisions until I have to, yet often people want an answer one way or the other. I've found that sometimes when people are planning to go out and do something, I may sound as if I am planning to go. It's not that I'm lying at the time. It's more that I feel like I haven't had time to consider all the factors involved. When the actual time comes, I'm more likely to weigh out a variety of factors (Would I be inconveniencing anyone or letting them down by not going? Do I want to socialize tonight? Does the majority of the group want to do something that I don't want to? - In which case I'm not likely to ask them to change their plans, but I might decide not to go if they don't really need me there, Am I just being my usual change avoidant self and should just go anyway? etc). One of my friends once called me on this, as he very much likes and needs to know ahead of time what to expect and it was throwing him off. I hadn't realized that it was affecting him or anyone else negatively (there was already a decent sized group of people that already knew each other well and often hung out together), or else that would have factored into my decision making.
As far as promises I can't keep - well, I know that I did a lot of that, especially when I first started teaching. I think it comes from a mix of truly wanting to accommodate and please other people, to the point of losing track of whether I can actually deliver or not. I'm not sure how it is for the people on the other side of the fence, but I guess I'd compare it to the way some people are about time. To me it is hard to imagine not having a sense of time flowing by and so being late seems like a selfish disregard for others. After having a couple of friends like this, I've realized this is an honest problem for them. They truly believe they can start out late, fit in a few extra things and try a new route on the way there and still make it in decent time! For me, I really do think at the time that I can do all of the things I'm promising, but lose track of what is actually reasonable and will realistically happen, accounting for life getting in the way sometimes too. I've learned that it works better to promise less and deliver more, but especially as a new teacher, that was a big problem for me.
I think there are probably other areas where I do this, but I can't think of examples at the moment that would illustrate them. Not sure if this is the kind of thing that OA is thinking of, or if it's more on a bigger scale that she is indicating.
Oh! The other reason I think that I may appear to do this is that I really, really hate disappointing other people. Therefore, if I suspect there's something that's going to be a problem down the road with us, I may have a gut feeling that something is awry, but until I can define and articulate it (which may take awhile), I'm not likely to verbalize it and I just continue on as normal. I think this probably feels misleading and results in deeper disappointment and blame (something I also hated even as a very small child, as the drive to please other people I care about is really hard-wired in for me) that would have happened if I had just presented it in a more batter-y form.
There's a little more here too, but I have to get it figured out in my own head better before I can verbalize it properly. Generally though, I think if pressured to make a decision sooner than I really should to feel good about it, I hear myself saying yes, even as my brain is saying, "Noooooooooooooooo!!!!". Then I have to work out what to do afterwards, based on how much upset it would cause if I changed the plan or on how I can make my own feelings come around or what other factors are involved that I haven't yet had time to consider. The default position is usually to accommodate by saying yes.
