is bleach: thousand-year blood war (bleach: sennen kessen-hen) episode 10 filler?

Suddenly regaining consciousness while hurtling upside-down and backwards through the air in Muken, 11th Division Captain Kenpachi Zaraki realizes that it has happened once again and flips over to slide back across the ground on his feet as he ruminates on having lost consciousness once again. With 4th Division Captain Retsu Unohana side-stepping several meters away from him, Zaraki rushes forward, briefly loses consciousness again, and continues clashing with Unohana while wondering how many times he has done this during their battle.
