is bleach episode 163 filler?

In her chamber in Las Noches, Orihime Inoue frantically runs toward the door, but is knocked back screaming by a Bala that hits it, creating a sizable explosion in the process. With the door knocked off its hinges by this, Loly Aivirrne sarcastically apologizes and claims that she tried to open the door for Orihime since the latter looked like she wanted to go outside, only to observe that she used too much force in the process as she stands next to a smirking Menoly Mallia.
