Disclaimer, I'm not a pilot so it's very possible I'm wrong. But I think you might want to ask your friend to clarify this as I'm having a hard time understanding. That said I think there's some terminology mix up. The path of the aircraft is taking when making a landing (the slope the poster is talking about) is called the glidepath. It's got nothing to do with the engines or the aircraft type. The stepping down might be the pattern used as the plane is being maneuvered to line up with the runway but AFAIK those are just to setup for landing rather then being a part of the actually landing itself once the controller clears the pilot land.
