unless you crash into something, MC crashes often are not that traumatic... if you slide... you get bruises and road rash... if you roll, thats when you get broken bones but rarely more.
This is far from the truth , the reality is it depends how you land , with or without a helmet you could crack your spine and be paralysed for life or break your neck and die.
Since he was the expert let's assume he knew the risk of dying was just as great with or without a helmet and perhaps he did not want the option of living like a vegetable.
