The following are my half-processional half-radical POV.
Autism and schizo- spectrums have a common base/mechanism: impairment of psychic functions (lack of empathy and non verbal commun, shallow feelings, social distance and similar). Their difference is autism starts at early childhood (maybe birth?), before any intelligence, language, soul and personality has evolved, while schizo/psychosis starts later (after teen age) when all these are fully developed.
The impact of each disorder on behaviour is different due to the different state it finds the rest of the brain. The maturity in schizo, for example, is the cause of its "positive" symptoms like hallucinations/delirium because the brain is full of images and words. On the other side autism heavily blocks social and verbal skills because it kills any "motive" of the brain to develop further from a very early stage.
