They've all seen is sword. He made it a point to show his release to everyone in the the 13 Squads when he was a Captain

Once they've seen his release, he controls their senses FOREVER. He doesn't have to release it again in this fight, as everyone here has already seen it.

Hell, they even even showed in the flashback of Momo's and Renji's training days that Aizen used to pretend to "show the trainees what a Shikai release looks like" just to make sure that all new Shinigami were under his power.
