is one piece episode 472 filler?

With Whitebeard stabbed through by Squard, the pirates and Marines are in a mix of surprise and horror at how Squard would go against his captain. Squard removes his sword while Buggy is in shock with his Den Den Mushi still online.

This leaves the people at Sabaody in an uproar. The pirates blame Squard for his action and Marco vents his frustration on the Maelstrom Spider pirate.

Squard demands that Marco kill him because Whitebeard is responsible for the whole ordeal. When the large pirate drops to his knees, Squard insists that the battle has been a farce.
