is bleach episode 281 filler?

In a small flashback, Aizen and the top three Espada are sitting inside Las Noches, planning to invade Karakura Town and create the Ōken. After Baraggan was hit by Captain Suì-Fēng's Bankai and is supposedly defeated, Suì-Fēng falls to the ground due to exhaustion, but is caught by Ōmaeda, who asks if she is alright, only for her to respond to Lieutenant Marechiyo Ōmaeda by telling him to stop doing that, as it is disgusting.

Hachigen Ushōda looks at the Shijū Saimon he had used to trap Baraggan and notes that Jakuho Raikoben being able to crack it is simply remarkable. He then looks down, asking if Suì-Fēng was alright. Ōmaeda yells out that she’s not, and she could have even died.
