I don't see anything wrong with analyzing social interactions. I'm not on the spectrum, and I still find value in it. My confusion what at what seemed to me (perhaps incorrectly) as an approach to conversations that tried to min/max against information disclosure.

You've clarified that though and it seems much more reasonable, although I'm still not sure why there must be information asymmetry. As an example, I just attended an office holiday party. Myself and a coworker I don't know well had a brief conversation on each other's family visit dynamics during the holiday season. I think we both fairly adequately covered our respective situations, and neither of us could come away thinking, "Wow, he/she knows all about my setup but I still don't know much about theirs". It was pretty equitable.
