The way I see it, the guy has by any reasonable standard entirely mastered bass playing.
His collection of videos, taken as a whole, look like the product of a high-functioning musically aware individual.
I'd think he's definitely smart enough to know what is needed for a scenario, and to decline to take part if he didn't fancy playing..
I suspect he'd be a delight to play with because he has plenty of mental capacity left over from playing to listen and create little details.
