At 10 kts it doesn't take a lot of braking energy to stop the AC with brakes if you are not in the grass emergency yet...If it really is an emergency your tires should be by that time exploding.
- don't wish to drag this out into pedantry, but the thread is about an incident where the brakes were probably almost ineffective so personally in such a situation I would like to improve my chances of stopping. Also, if as you say, you fly 767, you will have noticed the small 'kick forward' as you deselect reverse at low speed? Hopefully, also, MY tyres will not 'explode' until a little while after I stop
