I think they actually meant to say "It is likely that you will be thrown off the front of a YikeBike in an emergency braking situation - this is very easy as there are no handle bars in the way." :P

I really don't see how jumping off front of the bike is intuitive though. I mean, it's like trying to jump forward from the chair your sitting in. This in itself is an unnatural action, and to top it off the bike is gonna be moving forward when you jump forward off it. I foresee some severely bruised backsides.
