How does one lock the camera angle to the side as shown in the following video?

I'm not asking about the staircase hover itself, as I've successfully done that quite a few times. But it seems as though the camera angle shown in the video could make it quite a bit easier to do.

I've tried searching for more information on it, but have had no luck. And I've been unable to duplicate it.

Thanks for any help.

Just so you know in future, it's preferred if you ask your questions in the dedicated Q&A thread.

I personally have never been able to do it but it has been asked before. This was ZFG's reply:

Press Z, quickly move the control stick to a different direction than you are facing, let of of Z and press Z again, all very quickly.  The timing is a bit precise so it might take a few tries.

In the video you linked if you listen you can hear the Z-lock being released and repressed.

Why haven't I fixed the youtube videos in that page yet...
