I didn't realize until you said it, but yes, I do this for technical discussions too. Sometimes I've volunteered to write up a description of an issue on which I'm knowledgeable but not an expert, and when it comes to write it up, I realize there are subtleties about the situation that I didn't understand. So I just make my best guess as to what I think the situation might be, and post it to people who are the experts, knowing they'll correct any mistakes. It is indeed a much more effective way of getting someone to explain something than going back and forth with questions.

Some of my non-geek friends in a friend circle with quite a few geeks of different flavours call this "geek butt sniffing".

I've been accused of it often, when I meet someone new (who's a geek) and we do what in my head is the "geek subject matter negotiation", where each side narrows down domain expertise and experience by doing a breadth first tree search across all shared geek-domains, followed by a depth first search down the tree paths with significant crossover.

One recovering-geek friend says we're going "Pshhhkkkkkkrrrrkakingkakingkakingtshchchchchchchchcch" at each other before deciding on a conversation topic and speed...
