The "loop" isn't quite a "loop" because...
The Fizzle Bomber keeps changing the time of the New York bombing. When "The Barkeep" catches and kills him, he starts to become him and realizes that he must change the bombing time to avoid being caught. Of course he's still caught, but in a way he couldn't predict, and again the next cycle proceeds with a different bombing time.
