that whole thing reaches down to the core of typology.
once you encounter questions like this:
is someone an so-first instinctual stacking or Fe?
is someone energetic because they are 7 or because they are e?
is someone analytical because they are TP or because they are 5?
you have to ask what typology is:
if its semantics - behavioral descriptions - then 7 is just describing a type of extrovert, 5 is just describing a type of TP, and so on, so instead of "this or this", it would always be "this and this" - they are describing overlapping traits.
if it's mechanisms - naming internal processes - then there is real room to argue what behavior comes from where, and there is room for internal inconsistencies and people having one but not the other.
