He didn't die, he just shrugged it off. Facing a guy with Mangekyou Sharingan and not expecting rare powers was just an oversight, and Kurama basically said he was overreacting to being stabbed.

Naruto's a guy with truly insane healing powers. He withstood continuously being destroyed and healed, withstood his soul being ripped out, withstood having his Biju ripped out. Compared to that, being stabbed by a sword is nothing. It had simply been a while since he was injured in even the slightest way, and the reminder of what it felt like was unpleasant.

That's all there is to it, he should've been on guard for special powers and he overreacted to being stabbed. He was walking around just fine a few panels later. Against the other Shin he corrected himself and just defeated them easily with shadowclones and Kurama's presence, showing that he wasn't as rusty as some people suggest.

So the conclusion is, Kurama was being sassy. Which he has been doing since forever, including such things as embarrassing him in front of the other Biju and jinchuriki and saying he surpassed the other Hokage in stupidity. It wasn't more than a "hey man pay attention and don't be a pussy about the sword thing, you're fine"
