It undoes effects, not the cause of the effect, after that effect comes into existence. It might be almost instanteously afterwards, but afterwards nonetheless. Not before, as you state. So, it could potentially undo TWOH's reality overwrite or time stop, or the results of the time stop, but not prevent the time stop from happening before it happens.

This is, in some ways, superior to canceling an ability from being used at all, since many Stands have limits on how often they can use their powers, including all known Stands with time stop/time skip powers. DIO can't just spam time stop infinitely, so negating the effect but keeping the cause means he's now unable to stop time for a while.

However, I would like to point out that it's entirely possible that The World Over Heaven is either able to overwrite GER's power, or is in some manner immune to it. As such, GER might not be able to negate TWOH's time stop. Or it might. We're kinda in speculation territory here.
