They wouldn't. GER is essentially the same as any asspull "Deus Ex Machina" in other mediums of fiction, it's just that it got a conveniently overpowered ability to quite literally undo the actions of other characters. It's basically a poetic representation of the fact that Araki had given up on being creative with the abilities they had in the first place, many of which he had forgotten, and just gave the protagonist the power of God to end the fight.
