That's not true. GER doesn't "rewind" erased time because there would be no time to rewind at all, King Crimson erased it. It's very clear that GER is undoing the erased time itself with RtZ, hell GER literally talks to Diavolo during erased time. It also causes all sorts of weird bullshit to happen within erased time before it gets set to zero. Both the manga and the anime show that King Crimson's ability is still active when RtZ begins.

Tusk ACT 4 is really tricky. The idea that "infinite can't be set to zero" is kind of a misconception. Infinite is not an integer, it is a concept. So it depends largely on the specific kind of infinite that Tusk ACT 4 uses.
