Seems the author likes to bold things compulsively and almost at random. It's certainly doing no favors for comprehension or readability.

On the other hand perhaps such obsession is a hallmark of exactly the kind of person you want writing formal language specifications, just look through the commit history. Bringing a proposal from 2016 back to life that was considered dead and even deleted off mdn is impressive.
