In the spirit of debate, I can give an answer.
Pinch points are usually small well-defined locations. They a problem for people who are putting body parts into those locations, and are generally safe if the robot is disabled*. If you aren't touching the robot, you're not in danger. However, stored-energy catapult mechanisms can be a problem for people who are merely nearby. They pose a danger over a relatively large space, and it's often possible for such a mechanism to be fired even when the robot is completely powered off.
* If a pinch point can cause injury without the robot being enabled, I'm all for guarding it well.
