Sometimes people die even while wearing a helmet.
The only claim that can accurately be made is he probably wouldn't have fallen off the bike if he wasn't standing on the seat with his arms outstretched as it was moving.
Actually, you could also say it would be less likely
that he would have died if he had been wearing a proper helmet.
I agree that it would not be certain, but likelyhood would favor the life side more.
