Well Steve, it might and it might not. Given 18 bits of state (two bits/pistons
per leg plus two extra), we could have a total of 256K possible combinations of
leg positions. We only want about about 10 of them. If we start out the
pistons in one of the desired state combinations it will progress through the
magic sequence and get back to the initial state.
If we start it out in an unexpected state, it is hard to know what it will do,
but it probably won't get itself into a desired state. It will probably just
hang.
It would take a *lot* more logic (switches and maybe pistons) to make it self
correcting and get itself back into a good state.
So the short answer is *probably* not.
