I doubt it. Shifting under load causes nicks and peening of the plates, especially outer ones. It also forces plates outward on pins.
So we see stiff links, and breakage by plates coming off pins. However, I wouldn't associate it with an inner plate failure like we have here. (which, BTW is the 1st I've ever seen).
