I'm surprised that the air bag in that location is even that effective. Before the pedestrian encounters the airbag, they have already been struck in the lower body by the very front of the car, then roll up the hood before hitting the windshield. And while this may prevent them from hitting their head on the windshield or A-pillar, they are still likely to be thrown off the hood before everything is settled. So I guess in a situation that involved 4 impact points... making one of them softer is better. But this surprises me. Also, not every body even rolls up onto the hood. Depending on the speed, height, etc... pedestrians often just get launched out in front of the vehicle.
