Not correct. If you look at how escalators work (eg 3D animations), the step height is a variable that can be completely varied through the length of the escalator. So it can start flat, go up a flight, go flat again, go up again etc very easily and still be the same escalator. It works so simply it is amazing.

Reply to comment by rubseb in Eli5 why do stairwells need to be have two flights in a spiral to go up one floor when escalators can just use the one flight going straight up for the same distance? by exmxn
