is one piece episode 711 filler?

As some of the Donquixote Pirates' underlings exclaim that Lao G has been defeated, Roronoa Zoro looks over the enormous rift in the ground created by Sai's Kiryu Kirikugi and notes how destructive it was before deciding to keep Sai and his fleet in mind due to how powerful they are. Meanwhile, Sai runs up to the battered Chinjao and begs him to not die as Baby 5 states that she will make preparations for two ceremonies, a wedding and a funeral, which prompts both Sai and Chinjao to angrily proclaim that the latter is not dead yet.
