I mean, he might pay very close attention to everything at his company. That doesn't mean he's deeply involved with the engineering.
For all you know he had some technical presentations given to him by his engineers and is just repeating the info within. I don't doubt he himself has enough engineering background to follow or contribute to the technical conversations at Tesla et al, but yeah.
At some point you just have to reason about how many companies he has and how much work he already has merely being CEO or chairman of these firms and how he could possibly be doing day-to-day engineering decision-making on top of that. And given the very public and embarassing exposes we've gotten from engineers at Twitter, I have deep, deep reservations that Elon is really a saavy engineer.
