Kadaj did train with Grimmjow on a fairly regular basis, so when Nnoitra moved in to swing, he was aware enough of the risk to back off out of the way. That was the hazard of teaming up with Nnoitra; he didn't play well with others.

Normally, neither did Kadaj.

Nnoitra was holding back less, Kadaj could see it. It was probably for the best, with Orochimaru having drawn Kusanagi. It meant Orochimaru was actually out to hurt them now, which meant they had to rise to the challenge.

He took a moment to breathe, and charge another spark strike, letting Nnoitra have at Orochimaru for a moment.
