That thread has a quote from an interview, and then a bunch of random people saying he does.
I already know the mythology surrounding his engineering credentials. But I think perpetuating it does a real disservice to the real engineers doing work on these products. Do people really think that a bright, "well read" physics undergraduate can lead the practical engineering work on rockets and cars? I find it hard to believe.
I'm sure Elon sticks himself into tons of meetings, and hence has a lot of knowledge about what's discussed. And I don't doubt that he sets the goals for the engineers to meet, makes aesthetic and design decisions like some of the interviews suggest. But I think the guys Mueller manages are the people who actually make Falcons fly.
