If you are talking about 0:29 it just the camera angle that makes it look that way. Notice how when the beam goes all the way down, it doesn't touch the base of the claw until the claw folds. In the next shot you can see how wider apart the claw ends are compared to the base of the claw, and you can see two claws very clearly and that the beams are about the center of the claw gaps.That looked to me like a close call. It was definitely off-centre. A few more centimetres and it looked like the a claw would have hit one of the beams of the ascender maybe causing it to glance off.
