Sure, but what's described in the post is very much in line with very common descriptions of things autistic people struggle with - so much so that it's basically in the definition of the diagnose - and it's not something that is typically (or ever) being ascribed to ADHD.

Just because these spectrums are related and interwoven (together with other ones as well) in mysterious ways we don't yet understand, we don't need to treat them as one. Especially as laymen. They are separate diagnoses with different definitions. By, as laymen in a social forum where people often times go before even considering going to get evaluated, cross-ascribing symptoms between diagnoses we risk steering people in the wrong direction and they could potentially waste years thinking they have a diagnosis they don't have (according to our current health care systems).
