The math works out perfectly. It's called modulation (multiplication of 2 signals) and the subharmonic is clearly visible on the spectrogram. You can't combine two frequencies if the system is linear. So for example, in air, two frequencies never multiply, just add. A clarinet is controlled by airflow, so changing the airflow leads to multiplication of the two signals.
