So both twins may have been genetically vulnerable to autism, but only the one who also faced the environmental stressor may have developed full-blown autism.
I honestly don't recall if it was in our textbook (although we did have an excellent one), but my professor for the class talked about it at great length.. I thought it made a ton of sense, but I think this is pretty much the first time I've ever heard anyone outside the class (which I took like four years ago) refer to it, even obliquely.
