GER can only undo an action done to directly harm Giorno and resets anything that happened within the frame of that said action. If Pucci did directly attack Giorno, yes GER could undo it. Made In Heaven’s Time Accelerate forces an opponent into a lag where every non living organism and Pucci are rapidly accelerating. GER could be beyond that, but Giorno isn’t. Thus, Pucci would soon discover GER moving in his TA, keep his distance and force GER to expire or into an all new universe, technically defeating the point of fighting Pucci.

But hey, that’s just a guess.
