Even if he is a Reptite we have no proof whatsoever that all the reptites dies. In fact, they could have evolved into Mystics, as we know that the Mystics do not have a single leader or a unified kingdom (much like Reptites if a few survived the big freeze) until Ozzie and Magus came along.
But, yeah... he's probably just a man in a suit. It is a carnival after all.
