I think I know what happened. I think your friend put a pokemon in with a Ditto in the daycare on the 4th island and hatched the egg he received. Many people seem to confuse this method with cloning, though technically it is breeding.
The only way I know of to actually clone a pokemon, level and all, would be with a cheating device such as gameshark or action replay.
