Most airlines that do this board the rear of the aircraft first, then expand the boarded zone from the back forward. One of the greatest wastes of time is caused by people who are blocking the aisle while stowing cabin baggage. If you board the rear of the aircraft first, you minimise the time spent while people who have to walk down to the back are themselves waiting in the aisle for someone further forward to stow their baggage.
