Action… Naruto wasn't dead. He was in a critical state, yes. If Sakura hadn't been pumping his heart to avoid his brain dying from lack of oxigen, he'd have died for real. But he wasn't dead. Sealing a tailed beast in a corpse doesn't revive said corpse. And last time I checked, Yin-Yang release can't revive the dead.
