Incorrect, the physics tells you that the energy that was absorbed by the helmet would have been transferred to the skull/brain. All the actual testing of motorcycle and bicycle helmets is to failure mode so you know how much energy can be absorbed before it breaks or energy wave transfer through the helmets shell's and inner liner's medium and go into the skull/brain.
