I'm a little confused about how one valid two-word phrase can be a "better answer" than another.

A valid question. In puzzles or in a game such as this, I think a phrase that is likely to be familiar to more people is better than one which is likely to be familiar to fewer. If I'm playing along and an answer isn't familiar to me, I'll feel some combination of angry, frustrated, and cheated. I do not think the list of emotions a producer would prefer to engender in his game show audience include anger, frustration, or betrayal.
If the host explains the answer, that ameliorates some of that feeling with a "Huh. I didn't know that-- I just learned something," but I'll still feel like I had no chance of correctly guessing that answer.
So AMERICAN IDOL, a phrase familiar to anyone watching television (and therefore 100% of the show's audience), strikes me as a better answer than AMERICAN IDIOT, a phrase familiar to people who keep up to date with popular music (substantially less than 100% of the show's audience), in that it will be recognized by, and therefore be more satisfying to, a greater number of viewers.
