I think this is why the axle may be more likely to move on a singlespeed. The chain, while pedaling forward, pulls the axle both forward and up. The force, resisting forward or trying to pedal backward, pulls the axle both forward and down. Since there is a tiny bit of play, everytime it makes the transition from up to down and vice versa, it will slip forward a little, as well.
Having a derailer and access to large rear sprockets will actually increase the force pulling the rear axle forward and up due to the increase leverage of applying the force farther from the axle. Pedaling harder will linearly increase the force applied to the rear axle, but shifting to a larger rear sprocket will multiply the force on the rear axle.
