is bleach episode 353 filler?

In the hideout apartment belonging to Xcution, Yasutora Sado is informing Kūgo Ginjō about Shūkurō Tsukishima's attack on Orihime Inoue outside her apartment. He also reveals to Kūgo that Orihime has been feeling strangely familiar and comfortable when she thinks of her attacker.

Sado suggests that Tsukishima's Fullbring ability allows him to interfere with somebody's memories. He asks Kūgo if that was Tsukishima's ability when they were close allies in the past.

Frowning seriously, Kūgo asks Sado to tell him everything he knows regarding Orihime's experiences and feelings since being confronted by Tsukishima.
