The video of the crash is bullcrap.
That video is nothing like an actual crash. A highside is way more harsh than that.
He threw himself off the bike. When the bike throws you off, you fly a bit higher in the air than that.
It's one thing to do it on purpose, but when it actually happens, it's a different ball of wax.

I had a friend who wanted me to crash his bike for insurance.
He wanted me to lowside over a cliff.
I could have done it, but I wasn't going to get caught in legal issues if they ever found out what really happened.
