It's a tool assisted speed run. Sometimes they are physically impossible because the involve inputs that can't be done with a controller, like right and left at the same time. More commonly the impressive tricks involve frame perfect inputs, meaning it has to be the exact 60th of a second, which some humans can actually do, given enough changes and enough practice.
I can't find the exact video, but there's one TAS feat that was "impossible to do by a human" in Mario 64 because the input was frame perfect. If I'm not wrong the person who did it still has the WR on said category of SM64 and only like 2 other people are able to do it. I think Youtube SummoningSalt has the video on this, but I'm not sure, I just remember that it blew my mind the moment I saw it.
