Marcus,
I too am a little skeptical about the axle itself being compressed, but I think I can answer your question about nutted axles. With a nutted axle, the holding force is applied to the nuts and to the threads on axle that are outside of the dropouts. If anything, a force similar to tightening down the quick release would be found on the components inside the dropouts.
