I'll add that he may be showing some lingering relative weaknesses in social comprehension on the VCI, as his lowest score (though still well into the Average range) was on Comprehension, which, among other things, has some association with knowledge of social conventions. It is not unusual for high-cognitive individuals with social communication deficits to use cognition to compensate for social perception, by consciously learning the rules for social engagement to the point that it becomes "good enough." In fact, I encourage my students in this category to study people like an anthropology or wildlife behavior experiment, as a compensatory strategy.
