I wouldn't have a problem with that question and I'd answer: Team, scope for promotion/exploring other roles within the company in the future and commutability - in that order. Don't know what that says about me (or my interviewing technique) but that's how I'd automatically respond (because it's true).
The problem with the author of this is that there seems to be a smug arrogance in that he thinks he has invented a super special unique question which no one will have considered in advance, or have something in their answer kit that can be quickly and easily altered to fit the question. Which is exactly what you and some others have quite rightly done.
