Braking power of the front is far greater than the rear. The more brake you use (front and/or rear), the further forward your center of 'gravity' moves, the more effective your front becomes, the less effective the rear becomes - meaning in an emergency stop situation your rear is next to useless.
In a braking situation the use of rear + front over just front is only of additional benefit if traction would have been lost on the front wheel.
In this instance the guy's gone over the bars, the limit has therefore not been front wheel traction, the addition of a rear brake would surely have made no difference whatsoever?
