I should image it is like a prop, a prop under power bends forward because the prop forms a forward cone, and on impact the blade simply bends that direction otherwise it would have to lift the aircraft physically up off the ground to allow it to bend backwards. Either that or did it surge? I also wonder if the ice going through has hit the rear of the blade or the leading edge and with the cone effect that caused it.
