is bleach episode 340 filler?

Yushima's Zanpakutō stabs the Hollow and within his own consciousness, he can see Nozomi inside Yushima's as well. Nozomi calls out to Ichigo Kurosaki, but before he can do anything to help her, Yushima regains his will and attacks him, causing Ichigo's Hollow-self to break apart.

Now powerless once again, Ichigo falls to the ground, while Rukia slashes at Yushima, forcing him to back away. Rukia calls for Orihime to take Ichigo somewhere safe, but he refuses to go.

Yushima calls Reigai-Nemu Kurotsuchi to bring him fusion stabilizer to make the fusion permanent and when she arrives, she unexpectedly kicks him backward.
