Tom, amazingly enough, I actually remembered to check...
If I stand behind the slowly rolling airplane and move the rudder to the stops, the yoke remains locked. However, if I add some lateral force (i.e. shove the tail sideways), enough to stretch a spring, the additional angular deflection of the yoke will allow it to pop into full swivel.
Note two possible adjustments. Moving the rudder arm connection points inboard decreases yoke deflection for any given rudder deflection. Set that ratio so full rudder deflection doesn't deflect the yoke quite far enough to reach its unlock angle. Now, the additional lateral force necessary to unlock is a function of spring stiffness.
