is one piece episode 624 filler?

Back on Punk Hazard, Caesar Clown's former minions go in a search for those who were petrified by Shinokuni. All a sudden, Doflamingo appears from the sky and throws Baby 5 and Buffalo's heads back on to their body.

Before any of the G-5 soldiers could attack, Doflamingo uses Conqueror's Haki and knocks out a very large majority of them. Even then, the remaining soldier couldn't control themselves because of his devil fruit powers.

Doflamingo even has some of the G-5 soldiers kill each other demanding the whereabouts of Law. Smoker steps into the fight, launching White Blow at Doflamingo.
