9mm isn't an incredibly damaging round, so it's not the kind of caliber where you could shoot a person once -- or even four times -- and expect them to be out of commission. Interesting info about the need for higher caliber rounds here.
Whatever caliber, shot placement is also important, and you can never be sure that any of your shots actually does enough damage to physically incapacitate someone.
Thus the operational principle is that you shoot until the threat is neutralized, though not necessarily dead. In the video, she shoots four times and the guy goes down, but he's still moving and still hasn't dropped the knife. That's when you see her shoot again, and that's when he physically stops moving.
You might wonder why not just see what he does after he falls down? The reason why that's a bad idea is because he's already closed distance to the point where you considered him a threat, and if he's moving, it's very possible that he could scramble and reach you. You might be able to shoot him again as he does so, but gunshots do not necessarily cause instant immobilization (as seen).
To answer your question if a normal human being could get up after 4 shots and falling down, yes, it's very possible. If the person is under the influence of certain drugs it makes it even more possible.
Recent testing of the three major police and military calibers by the Federal Bureau of Investigation found that the .45 ACP was no more effective with regard to terminal ballistics than either 9 x 19mm Parabellum or .40 S&W. After two years of testing, one of the final FBI comments was that services that adopt (or stay with) .40 S&W or .45 ACP did so at the risk of increased recoil and a possible reduction in accuracy as 9 x 19mm with premium quality ammunition had nearly exactly the same performance.

9mm is a great round, and I'm not knocking it, but there's a reason the .45 was invented.
Yeah but the wiki says the following,
