If the snitch is both the trigger and the epicenter of this spell in progress, then this would explain how the three wishes will be granted by “a single plot”. The game is played/watched by mostly Slytherin/Ravenclaw students, so mostly Slytherin/Ravenclaw students would die. I can see a school like Hogwarts then giving both these houses the House Cup as a way to deal with the trauma for surviving students and honor the lost children. So that’s all three wishes: both houses win the House Cup, and the snitch is removed from Qudditch, all using “a single plot”.
The snitch will explode exactly at the moment when Slytherins and Ravenclaws have the same number of points, higher than the remaining houses. It will kill all students, thus freezing the house points.
This is what happens when you waste your wish on winning a stupid competition.

Or rather, Voldemort is the first kind of genie, the kind to whom no wish is safe.
