The tl;dr is that the comment on one engineer's tasks and the QA that one of the chores takes weren't intended to communicate that the team was 1 person big (or, presumably, that there's only one QA chore).
FWIW, my read of the wording around QA was that when a each new hardware platform is enabled, it takes 2 weeks for the whole team to work through their test cases. I assume, though I don't know, there's a lot of other QA done, such as when a new feature is added or something.
