I believe it means that, after he awoke, he turned everything into a white void. The castle had been destroyed, and the outside was empty as well. So we could assume he had erased the entire universe, and not just Wario's castle. The ending backs that up, as the universe didn't return when Black Jewel's realm was erased.

The rest was to prove the Marioverse is a universe through SMG. And Black Jewel should get Destruction, since he erased the universe's entirety.

The stuff about Rosalina's upgrade I'm unsure about, but I believe the opening could be solid enough to keep Low 2-C for Black Jewel.
