No. In both of your examples you cited Ne-leading individuals who are prone to sharing information with everyone anyway.
Even Comparative partners can 'look alike' because of a shared leading function. It might just be WA is sharing more now with point out of 'testing' whether or not she is ILE. IIRC, she mentioned in the past 2-weeks to a month that she was still considering IEE.
Besides, assuming yours and Jimmers' thesis is true, that identicals 'share more info right off the bat', the fact that WA is sharing more now with point could easily be an example that they are NOT identicals, since they have already known each other for years. /logic
My understanding is that Identical partners tend to avoid each other in social situations, and tend to interact with one another less. I'm unsure of the dynamic short-term versus long-term, or private communication versus social setting. If @
Jimmers read that they do share more info, I would like to know the source of where he read that, for reference.
