From the moment a MultiServo is broken, it stops working and no longer influences the object(s). The condition for a MultiServo to break is when a given distance or angle is exceeded. Regardless of its type, every servo can be broken by angle and distance. You can use this behaviour to break two servos between the same objects at the same time by setting the same breaking conditions for both. The "Break" parameters are the same for all MultiServo types.
