I agree with the both of you. In this context, the mirrored Mabel is to emphasize her reflected hair. It's comparable to the magazine cover. There's a whole host of reasons to be suspicious of the fez reflections. What the Mabel Clone Theory points out is hair being used to copy human beings, and Gideon's knowledge of that process.
