At about 1:18 in the video, you can hear the explanation: "In the case of a constructor method, "this" refers to the object that's being constructed."
So in this case it refers to the new Maplocation object. Since the base constructor has already established the values of "X" and "Y", the object can be passed to the map.OnMap method to validate the coordinates.
