New Scratch MTN: Landing - Support with hands is bugged?

From a reddit thread, it only works if you land from a normal jump and without moving. It will not work if you were photon dashing and just let go and fall straight down.

So basically you'll never see it in normal gameplay.

Can we get some official clarification on this?

From what I can tell you won't see the animation when you are in photon dash. You see the full animation on a normal jump or fall without moving. But when you land and continue to move forward, from a normal jump or fall, you may just see the landing of the animation or just the crouch.
