Glitched wounded stance?

Hello! I got a issue with the wounded mode. You know, when you’re on the floor, about to die. Well I got someone in the wounded stance while I was inside my base, I got out of my base to finish him off and take his loot but as I got out I saw see him stand up and start to run like nothing ever happened, I was like wot? Then I had to shoot him again to kill him for good.

Is it part of the game?
If not, does anyone have the same issue to where you can get up quickly after getting wounded, cause like, It took me 10 seconds to get out of my base after having wounded him.

You have around 5% to 10% to get up on your own, with minimal hp.
