If they used a binaural audio dummy setup and compared against a ground truth surround sound system it's possible this is machine learning technique to configure the setup. Sound propagation especially with specific speaker configurations (and ear positions) is hard to model. (Could use a non-machine learning approach to match the sound in the ground truth and construct a table of speaker configurations).
