is bleach episode 292 filler?

Ichigo breaks through a Garganta and arrives in the Fake Karakura Town. Ichigo appears directly behind Aizen and he uses this opportunity to fire a Getsuga Tenshō at Aizen.

However, the attack ends up hitting a barrier that appears behind Aizen. Aizen then greets Ichigo and immediately appears in front of the Shinigami.

Aizen swings his Zanpakutō at Ichigo, but Ichigo is able to dodge the attack. Aizen tells Ichigo that his attack was good, but the area he picked wasn't.

Aizen explains that a creature’s biggest blind spot is in the back of their neck and that he wouldn't have gone into battle without the proper protection.
