Never heard about Zed so consider this rather objective - I just read the post and I don't think I agree with your take on it:

Just because he hadn't thought about that particular language horror side effect doesn't mean he doesn't understand C

But UB is such a key aspect, if you don't understand in full what it is, I'd say you do lack some understanding of C?

And no, he doesn't mock people who read the standard.

It is open to interpretation, but you should admit his Ahhh the "undefined behavior" trope, whereby a C "expert" who's memorized a standard trots out the abstract machine to justify his point. is rather snarky
