You can't use another skill because Flare leaves you at 0 MP.
If you're not standing in Leylines, the instant the first MP tick comes in, you start casting Fire 3, and the cast takes long enough that you'll get another MP tick. This provides enough MP to do 2xFire2 + 1 Flare after that, thus repeating the cycle.
