I'd say that they're abilities manage to negate each others. One of them could erase the other from existence but the erasure itself could be erased by the other, and this could go on until they realize its not a battle of their powers, but their physical self, resorting to punches instead of reality warping.

Of course, I doubt any reality warper would have any knowledge of martial arts. They'd have no need to learn it prior to meeting each other.
