The Astral Plane has a lot of invisible barriers. The only barriers from this map that are visible in the game, are the thicker red ones. They look like normal walls in the Astal Plane. The rest is invisible. The Astral Plane is not a fixed 'room', but rather a continous, possibly spherical place. Thus, stepping west off the map, takes you to the far east of the map and vice versa. Stepping north off the map, takes you to the far south.
