You didn't notice the semi-colon. And actually I was wrong, because it's a post decrementation, so it would be -1 or the maximum integer value if it is unsigned.
I just didn't notice it because there's literally no reason to ever do that. my brain glazed over it, assuming that it would be one of the most pointless things to do to utilize it for that purpose.
If you want to add x processor cycles to the assignment of x, instead of just using a single cycle, then by all means. But I can't think of a single reason where that would ever be useful.

What does it do?

It slides the pointer to X down along the memory address rows until it's on the same row as the pointer to Y.

Still waiting for the punchline…

Hey, did you get your punch yet? Or are you still waiting in line?

So while(x --> 0); is another way to write x = 0 (assuming unsigned integers).

No. It's equivalent to while ((x--) > 0)
Or while (x > 0) { x = x - 1; ... }
