The reinforcement types in a stair slab are top, bottom, and distribution. The purpose is to reinforce the stair slab, similar to any structural flexural element.

As OP does not see value of a picture, I went a-Googling for one.
Maybe E1 and E2 here ? -

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Exactly. The top steel is there in anticipation of hogging moments near the supports. I always find things a little confusing at the landings. For example, in the photo that you posted, I doubt that little support beam at the bottom right really offers much torsional resistance. As such the waist slab is probably in positive bending almost all of the way to the wall. The detailing usually ends up supplying both top and bottom steel in these areas so we're probably covered either way.
I'd never heard the term "waist slab". Always good to learn something new.
