I think what they mean by "torque limiter" is that the "P-ring" compresses completely until the outer base circumference edge of the can makes contact with the seat. When the can hits the seat, it's on all the way and doesn't require any more torque.
With a filter that has the conventional flat "O-ring", you can over torque them past 1 turn, which will cause them to lock-up big time when it comes time to remove them.
