Overshearing

It certainly can be. I have to be careful not to do it myself, and often lose that battle! Then again (and this isn't a criticuism of your use of the term, it's the best shorthand we have), the notion of overshare is a very neurotypical-skewed concept. The sort of thinking that means that 'how are you?' really means ' Just say the word 'fine' please, it's a social convention' ... for example. Encoded into much of 'normal' factory settings for conversational exchange is a 'keep it largely to small-talk, and don't say anything too esoteric or tangential as we go from A to B in the fewest moves possible'. Which is hard for many of us in this community to do. Though of course, being taciturn and situationally mute is just as common with us - and some of us (me!) can go into either mode depending on any number of factors. I tend to overshare in a one-on-one, but find it hard to push even basic phrases out in groups.
