Infinite waterfall - a possible solution

I recently posted an interesting video of a seemingly infinite waterfall, but I'd like to bring it up again. Why? Because an endeavoring BoingBoing user has taken the time to present a possible solution to the problem.

The solution he presents is actually quite close to what I speculated in my earlier post. The only real difference between his solution and mine, is, I believe it could be done in one take, while he says it took two. However, until the author of the original video says otherwise, it will still remain a mystery.
