I don't think mentioning you're autistic actually clears that up. Would probably be better to mention the association thought process without leading with the diagnosis.
It's cleared up separately, immediately after that mention. The thought process appears obvious because it makes logical sense once explained, but people don't always intuitively infer it, if that makes any sense; it's difficult to explain, but I think my comment was perfectly sufficient. I suppose the mention of autism was meant as a qualifier for the information that follows; sort of a "here is why my brain works this way" before the actual "here is how that comment happened the way that it did".
While I hear what you’re saying and I agree in general, I think what you’re reading is that in this case the logical jump was fairly obvious with or without the mention of your diagnosis. I have ADHD, and it seemed very obvious to me.
That said, you can be as open as you want about your diagnosis. I didn’t think there was anything wrong with your comment.
