It wouldn't surprise me if they did the latter. The oxygen saturation sensor is fundamentally just another optical sensor with a different wavelength of light -- so if you feed all three wavelengths, plus the accelerometer, into a neural network, you may be able to pick up on oxygen-related physiological signals without explicitly processing an oxygen timeseries.
