That would mean that Sauske's genjutsu also tricked Madara. Considering how little Madara think's of Sauske's power, I doubt that this is the case.

If it is, then we could start walking down the "oh-shit-my-apprentice-out-power-leveled-me-while-I-wasn't-looking" scenario.(I.E. Madara trying to kill Sauske at a convenient time because he's gone from asset to threat).
