Fairly sure you just witnessed a Xil typo, since Kubo said Grimmjow was not dead prior to the start of the Blood War Arc.

The point I was making is that we cannot assume Kira is deceased, based either on his injuries or his disappearance from the manga for, admittedly, like two years. Hiyori was literally cut in half during the Fake Karakura Arc, but she's fine. Ichigo has 'died' three times since the manga started, yet he keeps on kicking. Hitsuguya got hit by all the fires during his clash with Bazz-B, and then vanished for dozens of chapters, only to reappear kind of alive. The point is, things in Bleach don't happen until they are stated by Kubo as having happened.
