Hmm maybe I'm misunderstanding, but each red dot represents the average of a collection of views

The idea behind PG's article (as I understand it) is that "the left" and "right" have some degree of arbitrary positions they support, so the chances of any individual independently coming up a set of positions that perfectly matches is extremely low.

But individual positions could very well be scattered across the spectrum, some very left, some very right, but together would likely average out to near the middle
