I'm a little cautious about going too far off-topic when the conversation has suddenly become interesting again, but given my basic understanding, the function from which the alpha protection AoA is derived provides a small buffer zone between that value and alpha max - the reason being that alpha max is the highest AoA the wing can achieve while continuing to provide sufficient lift (as an aside, the alpha floor trigger function computes an AoA between the alpha prot AoA and alpha max).
If the Normal Law protections were to stop dead on alpha max, then even a relatively minor change in the airflow over the wing could conceivably cause the AoA to exceed alpha max and consequently stall the wing. I used tailwind only as an example of change in airflow.
