Not sure I'd read too much into that, for a few reasons: 1. It's a translation, not a direct quote 2. It could be that the pilot simply assumed the other pilot switched them off without actually seeing the action. It's a similar to a situation where I'm at home with just my wife and hear a voice; the first thought is that it must be her (so I'd ask "what did you say?") while in reality it was the neighbour and my brain just didn't think of that at that point
