This effect is indeed strange, and rare, and underlines the severity of the mechanism and the result. It is mentioned and described somewhat in the Norwegian articles that are linked to. As I understood the Norwegian text, there is severe clotting in unusual places like the brain and stomach, and the blood is effectively left void of platelets. As I understand - as a layman - is that an autoimmune-related reaction causes what I would consider to be an implosion of the platelets. This is still rare, but it will of course be investigated and we will of course figure out why this happens, and then it probably doesn’t have to happen to anyone! Maybe there’s a genetic component ¯\_(ツ)_/¯
