There's a bit of a difference between the online translations and the Viz translation in volume 60 concerning this. The online version has Kensei telling Hisagi he'll probably die if he doesn't RELEASE his bankai, while the official English translation by Viz has Kensei saying he thinks he'll need to ACQUIRE bankai if he doesn't want to die. That's enough to cast doubt in my mind.
