I think the production company were running behind or something, so rather than the normal one or potentially 2 recap episodes often seen around mid series they did 4.
I beleive the Distributors in the U.S. deliberately worked out the episode count on the disks so that they could put all the recaps on that one disk so people could skip buying it if they wanted.
