I think they are just to allow for easier turns, but I can't say in a truly educated way.

Yes , DB tractors were built to do this, when using there reverser system. You had to change out the orginal hubs and dog, replace them with a sliding in the hub unit. This basiclly let you have a dog for forwards, then by pushing the R rod, the center off the hub turned and the other dog then grips the hub. I also have an edko tractor that does this in a more complicated way using an internal spring.
Easier turning & "free-wheeling". I don't think many or any of the ones with the dogs had any kind of reverse.
