Airbus rolls over Ramper's foot

I saw this in the FAA's incident/accident summary the other day. In Portsmouth, NH an Airbus A319 rolled over the foot of a ramp worker after it was disconnected from the towbar. Doesn't really say which airline or to what extent the injury was. If he had steel-tow boots, though, wouldn't the weight shove the steel cap right into his toes? I'm sure next time he'll check with the flight crew to make sure brakes are set.
