The problem lies with the shank of the cocking piece pin not being surface hardened like the bolt body is. As a result as the pin rides up and down the typically sharp cam cut in the bolt body, over time it gouges away metal from the pin until ultimately it fails. As the video creator notes, this isn't necessarily a bad thing as it's better to have the pin wear than the bolt body itself as replacing the pin is a much easier affair that wouldn't likely necessitate resetting the headspace on the barrel.
The fix, as shown, is quite simple and easy to accomplish with a Dremel or even just a fine file or some emery cloth. One just needs to debur the cam cut and polish it up.
