He used the Pure Hearts to nullify the invincibility, but even without invincibility, Super Dimentio was still powerful enough to destroy the multiverse, and Mario defeated him using only standard equipment (heck, it's more than possible to defeat him without using any items).

Also, let's not forget Mario's ability to flip between dimensions. He could simply flip to 2D to make it impossible for Hyper Sonic to hit him.
