It doesn't double your spell damage.

All it does is make your basic attacks and single target spells (Q/W) do additional damage equal to 6% of your current mana. Each time you do this additinal damage, you lose 3% of your current mana. (This is where the double damage comes from, because when you double 3%, you get 6%.)
