That's interesting to read. Asperger was a pioneer so some of his generalizations are not widely accepted today, such as attributing homosexuality and sadism to his patients. I've read some autistic adults' descriptions of how they used to enjoy provoking people as children because it produced such interesting patterns and colours, but even for those who have that trait it's not sadism.
Needless to say, his observations are based on a very small sample of people. But some of it is uncannily familiar.
