*Is instantly behind you*
Unfortunately for your spell that works "once it has been cast," it hasn't be cast yet.

To that end, it would be true, if i had left it unmodified.
You see, once cast, it continues to exist on the affected target in multiple points in time, before and well after.
Kinda why i needed some of your energy.
So just because you undid the process doesn't mean you've undone the spell.
