Isn't this (kinda) true, in general?

I work at Google. Many of the "official descriptions" of various levels include "size of team" as part of the description. I think, generally, anyone in a middle management position, particularly at a growing company knows that "more people equals more advancement".

Yeah. At many places, team size (and eventually, number of teams you manage through other managers) is codified in manager role descriptions.
