Talking in terms of only the unweighted stability of the cam think of it this way: what is the force of the cam lobes against the rock?
Where does the force come from? Two ways, the spring tension which is variable depending on how far the lobes are retracted. And gravity. In a horizontal, the lower lobes have force equal to the spring plus the weight of the unit and sling and biner. The upper lobes have force equal to the spring force minus the weight of the unit.
Since the lower lobe have more force on them, a wide stance seems reasonable. Seems like you could fairly easily test how much the device walks but trying it both ways and jiggling the rope is a hopefully reproducible fashion.
