Well, undersea is more specific than underwater. It's true that the changes in chronology and description weren't really mandatory, since we could just write it off as using a descriptive phrase instead of a name reference. But the problem is that "Underwater Temple" was capitalised, which implies that it's a name. If it was "underwater temple", then it really wouldn't have made much difference.
