"Autism" winds up being a catch-all category for all kinds of social challenges. The label is frequently a means to largely write someone off because real help would be too much work.
One thing you frequently see in severe cases is faceblindness. Faceblindness is itself seriously socially impairing. All other things being equal, a faceblind person will have greater social challenges than a non-faceblind person.
If you can identify the myriad specific things going on with a socially impaired person and address each of them, that's usually more effective than calling their social impairment "autism".
