The rotor is on a shaft which is free to rotate a small amount as the centrifugal advance weights swing out at higher RPMS. If you take out the breaker plate and look, you can see this mechanism. There should be two fly weights, held in by a couple of springs, and a cam mechanism to advance the rotor shaft when the weights are extended. If you are remarking about the ability to rotate the rotor, and if it returns to the same point every time when you release it, there is no problem, relax. If, on the other hand, you can make it stay rotated when you advance it, your advance mechanism needs service. Lastly, If you are talking about being able to move the rotor sideways (not in pure rotation), you've got a badly worn out distributor - I'm amazed the car will run that way. The top bearings are totally shot!
