I guess I don't understand the reasoning.
Explain for me?

Because when the engine truly rotates backwards, the valve timing will result in instant piston to valve contact; even rotating by hand, the mechanical advantage is sufficient to bend valves. When you back off of WOT, the engine is still rotating clockwise; the only way to get it to rotate counter clockwise is by someone turning the crank backwards.
