Very likely because radio did their work correctly (with the misfortune of a wrong prelim assessment), but the requesting doc either forgot or chose not to act on the results. Or results were not transmitted correctly, so the requesting doc never was aware... many things can go wrong in collaborative work. Anyways, a communication issue for sure.
