What exactly is Jump Recovery Volume?

I did it, I have no idea if it was intended, but this challenge was really fun, especially trying to figure out the way up.

It is indeed able to be completed and I've had people even full clear it. The very end requires the use of a Jump Recovery volume which will take you to the top floor , thus why you're recommended to look into the original level.

This IS meant to be completible...right? I'm just shy of the top floor, but it seems like the only solution from here is to wall climb between two ropes (atrociously bad surfaces to even wall grab onto once). Nothing else seems to be high enough or in a favorable position to get to the top, and there's nothing nearby that's able to give a vertical speed boost.
