This makes no sense.
I'm really skeptical of this "disorder." I think it mostly amounts to "semantics and variability in human abilities, not pathology."[1]
Metacognition like this is super slippery and is really easy to draw whatever conclusion you want. I've just never been able to draw even mildly realistic anything ever, this doesn't mean I have a disease.
