This view of the staircase reveals that the connection between A and B is only
an illusion. With a 2D representation of the staircase, it is possible to choose
exactly the correct point of view that would hide the gap between A and B.
Without the beam in the picture above, there would be no way of knowing whether
B was one step up from A, or the continuation of the staircase that wraps around
the front of the picture.
