is bleach episode 193 filler?

Szayelaporro Granz watches on as Renji Abarai fights one of his copies. Renji comments that they look nothing alike, reducing the copy to goo which sprays across the chamber.

He comments that even though it is as strong as him, a fake is still a fake. Uryū Ishida destroys the copy that he had been fighting, also reducing it to goo.

However, new copies emerge from each pool of liquid. Szayelaporro acknowledges that the fakes are not very strong, but reveals that each time they are defeated, they break apart and multiply.
