This isn't necessarily stupid: If you cast a spell early on in the game, and it's crucial to your empire, the gems you put into it early on may not be sufficient to withstand modern dispels: Thus, you cast it again, overwriting it with a more powerful Version, so that you don't risk interruption of service and the messiness of trying to cram a spell into a global slot.
