I do this simply to keep on top of dishes. I always run the dishwasher at night regardless of how full it is. If it's significantly full after lunch I run it then too, even if it's not all the way full. Otherwise, when dinner comes around I likely won't have room for the additional dishes from that and would need to do a cycle before going to bed, wait for it to finish, then empty and load it with the leftovers.
