I know, but this is a difference in how normal people and search people talk about SERPs. "Ranking factors" almost always refer to organic search. That's part of where this friction has come from. Personally, I wouldn't be surprised to see the carousel disappear once Google deems that AMP has become self-sustaining. I think they're using it as motivation to get publishers on board, and then they'll fall back to regular organic ranking afterwards (to which AMP pages will still benefit). But in the mean time it's causing a lot of consternation.
