I'm of the belief that warping Gajeel was akin to a combination of the suicide attacks by the 9 Gates. He was already dead by the time Gajeel delivered his final lines and it just so happened that the alteration to space displaced the trajectory. The actual spell was finished but the outcome was altered. Something vaguely along the lines of like how Edo-Jellal reversed the anima.
