You'd pull the rope to retrieve your cams and it would remove first the tighter short one, then the looser long one. Technically, you could pull this off with as many cams as you want. Here's a Majid-like MS paint-o-gram. You could go half the rope length, too, unlike the measley third you get from the sport TRT. 
I set this up and tried it yesterday in a horizontal at about head height. Worked like a charm.
Some observations:
1. Deep cam placements were harder to clean than less deep. I'll leave it to individuals to find their own balance between safety and ease of retrieval.
2. Placements that were closer to the overcammed end of the spectrum were also more difficult to clean. I found a placement somewhere in the middle (leaning ever-so slightly toward undercammed) to work best.
3. I sometimes needed a good stiff yank to clean one or both cams, which leads me to believe that the more rope you have in the system, the more difficult they might be to clean (due to rope stretch).
4. Constricting placements were significantly more difficult to clean. Parallel-sided cracks worked best, but slight irregularities were also doable.
5. Somebody above mentioned that the weight of the rope hanging on the triggers might cause the whole shabang to fail. This may be different in vertical or bomb-bay cracks, however, in every trial, I had to pull harder than the weight of a rope to free the cams. Also, I don't think it's possible to clean the cams with a person's full body-weight on the rap line. Still, avoid throwing the retrieval end of the rope before rappelling.
Use your own judgment about your cams' landings.
