As the pump puts equal pressure on all four slides, the one with the least resistance moves first. When it completes its path (or hits a sticky spot) its resistance increases and the one that now has lowest resistance moves.
So typically, the smallest one or one with lightest load goes first and one that's largest or heaviest-loaded goes last--in either direction.
