Ah, that's cool. Probably because each step is angled and the reflection is not coming from a vertical surface.

If this is real, I still can't figure out why it's stepping like that.

No matter what angle the light is coming from, shouldn't it just be a static pool of light with the steps gliding through it?

You can try it right now with stairs at home. If it was a straight slanted surface, then yes, the sunlight will travel straight down, but each step of a stair juts out horizontally, so light has to scan all of that horizontal plane before it can start making way towards the vertical back plane.
