Fleuri had a split second to realize what the griffin was doing, and that he had made a rather glaring mistake.  It wasn't going to try and pull him off using its claws, it was going to slam him into the ground.  He knew immediately that he had to get off of this beast before it crushed him.  His armor wasn't made to stop something like this.

Getting crushed was a risk when riding a horse, too, but this thing was much heavier, and he didn't think that the feathers on its head were going to cushion the impact.  However, there was one thing going for him compared to a horse- there were no stirrups to hold his feet in place.

Using the arm that was still holding onto the griffin, along with the leg on that side, he flung himself to the side, away from where the creature's body was going to hit the ground.  Simultaneously, his other hand let go of his sword so that its not-inconsiderable weight wouldn't slow him down.  It was a risk disarming himself like this but it was a much bigger risk not shedding the weight, and he didn't have enough time to think it over.
