I guess you’re the expert here since you Googled a condition & now you know everything there is to know about it, right?
let me break it down. over 12 years ago when I was diagnosed, among the better-known symptoms like mixing up numbers, “misremembering names” (especially those that start with the same letter/sound) was a frequently published symptom of dyscalculia (and dyslexia, FWIW):
fast forward to 2013, in the DSM-5 they changed the definition of dyslexia and dyscalculia, removed them as diagnoses and instead replaced them with a more general diagnosis: “Specific Learning Disorder”, which among other things now requires that a person is “unable to perform academically at a level appropriate to their intelligence and age.”
in my opinion, and this is just my non-professional opinion:
if I tell someone I have a “Specific Learning Disorder” they’ll generally have no idea what I’m talking about. it’s easier and feels more self-consistent to tell them the name of the condition I was diagnosed with, even if it’s outdated.
the new DSM-5 diagnosis doesn’t account for people like me who were able to excel academically despite difficulty with numbers and names. did I have to read numbers 10+ times to make sure I knew I had the right one? yes. do I still struggle immensely to do basic arithmetic in my head? absolutely. am I also a software engineer who sometimes has to work with numbers? yes. did I get straight A’s in all my math classes? yes. people with dyslexia and dyscalculia excel all the time by discovering and using their own coping mechanisms, so this diagnosis seems overly reductive to me.
again, I’m not a professional. is it possible that my symptoms which were previously attributed to dyscalculia are just a part of my ASD? sure. but I’m pretty sure if I said I have trouble remembering Elliot Page’s name because I’m autistic, people still wouldn’t know what I was talking about, and I’d have an even harder time explaining it. so there you go.
