We don't know the real reason yet, but i couldn't get my helmet off after i broke my collar bone and that breaks easily. I had also 7 ribs broken, but hands were ok. Tight leather will also resist. Maybe i would have managed after while, but it felt desperate. If helmet is full of mud and you can't get your helmet off or hands up to dig mud off, you are quickly in serious trouble.
