Apparently this is something that actually exists and you can buy... looks like an AI-fail to me, but maybe it has some advantage over at adjustable wrench and vice-grips? https://www.amazon.com/dp/B08L6V5WV8

Yeah, that's the whole point of it being a worm gear right? They are very hard if not impossible to back feed. By the time the wrench gets sloppy enough for that to matter, it's time to replace the wrench.
But looking at it, it might actually open up and clamp down a bit? With the whole part moving in and out? That could be useful.
It might also be easier to use if someone has only one hand.
