The number describes where the repetition begins
A line dance choreography often consists of a sequence of steps that you dance several times. What matters for the wall designation is which direction you are facing when the next repetition begins. The directions you face in between are not counted individually.
In a 1-wall dance, each regular pass begins facing the same direction. The sequence can still include turns: you can face a different direction along the way and return to the original direction when it begins again. In a 2-wall dance, the sequence starts in two directions, usually alternating between facing the front and the opposite side.
A 4-wall dance uses four starting directions. As a simple example, imagine a sequence that ends with you turned a quarter turn from where you started. That means the familiar sequence begins facing a different side of the room the next time. After four regular passes, you are facing the original starting direction again.
The designation doesn’t tell you how long the sequence is or what its specific steps are. One named example is the Tush Push with its 40 counts: the length and the direction you face are two separate characteristics of a dance.
