The term is maybe more my own invention than anything, but I think it's an accurate label for contexts where you just have an association, or you don't -- no rating. In this case, recommenders still work but I don't think they can be said to be estimating ratings. What you get from estimatePreference() for these implementations is useful for ranking but isn't really an estimated pref.
