There are a few similar runs of other game sets on TASVideos:
While some consider TAS runs as "cheated", they have their own niché, because usually they are pretty entertaining, showing what can be achieved in the game that's otherwise not possible in real-time runs, showcasing game glitches, and so on.
I was under the impression TAS stood for Tool Assisted Speedrun.
This level only exists to be run as a TAS: https://www.youtube.com/watch?v=NuRQjaOhwGM
If someone referred to, oh, Paris Hilton's dog as a VIP, would you really want to make the argument that VIP actually stood for "Very ImPortant"?
I'm pretty sure that is a re-definition of an acronym that began life as "Tool-Assisted Speedrun". It's worth noting that the video you linked to talks a lot about "saving frames" in its description - not something anyone would care about if speed wasn't still a thing on their mind.
That doesn't change how every YouTube video of a TAS has comments along the lines of "this is dumb, ur cheating lol". But YouTube comments are always bad.
