Thanks for the link to the paper. It's definitely more interesting than speculating about one sentence. Cherry-picking to support my point, at the end they say that they cannot know if people actually made the food choice on the basis of affect or cognition, or if they thought about their choice when asked and rationalized it in terms of emotion or cognition. So at least they admit that. They also say that their foundational model "seems to be consistent with recent work by neuropsychologists", which again is fair enough, in that "seems to be" means they aren't making a hard claim.
