I'm unfortunately not very skilled at graphics nor image manipulation, so there isn't a very viable way in which I could demonstrate this with visuals...

I'll try reiterating: you are aware of how operates, yes? It is always cast so that the wall is perpendicular to the direction in which Yas is facing (ie. it is cast foward). The W functions just like this, except the wall's length is global, and will always divide the map in two.
