You could do the same thing with an escalator by having a landing in the middle, and this does happen at times.

Technically that is two escalators which increases the cost.

Yep.

(Of course two flights of stairs are also two flights of stairs. But yeah, the cost thing.)

Two flights of 10 steps are not significantly more expensive than one flight of 20 - all you're adding is the landing. Two escalators means twice the mechanical equipment.

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.
