Ni goes all the way to the bottom of one system to fully understand all of its implications and remove itself from any unconscious perceptual bias in interpreting the meaning of that system, but doesn't make the "horizontal" inter-systemic connections that Ne is capable of.
Statements like, "You know, x is a lot like y in that the relationships between their parts operate similarly" are Ne. Horizontal connections between the same level of depth across different systems. Extroverted functions are by nature more superficial.
Statements like, "You know, x is really just a shallow attempt to deceive me, but there are a lot of different things I might be missing before I step back and view the system independently of its built-in interpretations" are Ni. Vertical connections down to the deepest levels of personalized interpretations of meaning.
Just because Victor uses abstract language to illustrate his points doesn't mean he's using Ne. Except when his Fi takes over and makes unsubstantiated moral pronouncements, he's always seeking to show how everything is all in how you look at it, which is classic Ni.
