is bleach episode 361 filler?

Following the revelation that Kūgo Ginjō has been the enemy all along, he stabs Ichigo and declares that his Fullbring belongs to him. An injured Uryū Ishida looks up from the ground towards the stabbed Ichigo, and thinks back to the time that Kūgo had attacked him using Shūkurō Tsukishima as a decoy.

When Uryū had been chasing Tsukishima, Kūgo attacked him from behind before he had time to react. Once their target had been cut down, both enemies stood over Uryū's injured form and discussed their plans.
