It sounds like both of you are referring to an asymmetrical time constant that is longer on the downside than the upside in order to momentarily hold the display capture near max reading. Even if this is the case, there are other issues with this test, such as asymmetric air currents and displacements when breathing in and out, which could create a bias where the sensor is located, the duty cycle of in/out breath flows, and a natural tendency to pause closer to an exhaled state, unless you are undergoing Wim Hof training.
We already know that students lack perfect regulation of breathing via low-oxygen feedback to maintain optimal oxygen, as evidenced by yawning.
And we already know that research has been done on working, standing, surgeons - arguably more active than students sitting at a desk - indicating mask-induced deoxygenation during surgery:
