Autism and OCD are "co-morbidities". I think autism begs being obsessive about certain interests, but OCD is really its own thing and, as noted above, is related to anxiety.
I know I am autistic. I also know that from age 10 I have only been able to eat cookies (Oreo, Nutter Butter, Chips Ahoy) four at a time; I will eat two on the occasions where there are two or three left, but never an odd number. That to me is plain old OCD.
Yes. The "obsessions" of OCD, and the "obsessions" of aspergers/autism are two VERY different types of animals. Shouldnt even use the same word for the two things.
An OCD person will become "obsessed" with door knobs because of fear of catching germs, and will wash door knobs, and wash them again. And steam them, and spray with disinfectant. And this person may become ashamed of their obsession, but that shame just feeds into their fear of germs, and their compulsion ...to wash and sterilize door knobs even more.
An aspie who gets "obsessed" with door knobs because he/she just digs doorknobs. And will collect door knobs, fill a drawer, or a closet with prized collected door knobs, and will buy coffee table books illustrating the history and evolution of door knobs, and will bore folks at parties with their excited monologuing about door knobs.

A NT might...see a business opportunity in doorknobs, and become obsessed with finding ways to market doorknobs to the general public to make money.
