I think Ne is about seeing similarities of properties between objects. Like, when you look at an object you see how it can be like something similar. I'd also like to think Ne types are good at seeing alternative scenarios.
It's opposite of Se in that Se sees things as they are while Ne sees how it could be like something else.
Ne PoLR tends to result in problems seeing alternative scenarios. ESI might see someone being rude and become enraged. They might fail to see that the situation was different than they thought. XSI are quick to see how someone is wrong, but may fail to see beyond the apparent situation.
This is my take on it.
