Having the boot stay on your foot is certainly a key issue ... but I've seen even Sidi boots come off, depending on the forces of the off. When the Sidi's came off, the boot had caught and the forces popped the zipper. The foot and leg came out and the rider continued flying further away from the wreckage.
I halfway think that this was better than wrenching and breaking the lower leg or ankle had the boot stayed closed, but I don't know if Sidi's are made to do this, or if it was coincidental. I suspect the latter.
