It's a way how autists empathize with others beside for example resolving problem/issue. It's also a way to show we are at the same level. I lived the same experience therefore we're the same. Autists don't like (for a part of them) the idea of superiority and inferiority. It's part of the fact to have a great social justice mind.
It shows that we have a great sense of socializing and in multiple ways. It's shows again our great capabilities to communicate. It's not easy to open ourself to others in a personal way. It's requiring efforts and energy. This is the opposite of the lack of communication and socializing.
We have to remember all of this is unique to the autist opening an infinity of possibilities.
