To avoid the aircraft looping around the waypoint in case it misses by more than the WP_RADIUS an additional check is made to see if the aircraft has crossed a "finish line" passing through the waypoint and perpendicular to the flight path from the previous waypoint. If that finish line is crossed then the waypoint is considered complete.
