Anecdotally, yes. In my experience most projects are carried by a select few 'Heroes' doing the majority of the difficult implementation and innovation, tied together by a larger volume of less impressive but still critical connective work.
From my reading, the author's suggestion is that, functionally, most teams understand their goal and how to work towards it without regard or 'real' benefit from an overseer.
It's a strong claim, and one that should be relatively easy to test if an organization or research team wanted to.
