This interested me, I recalled hearing that SAM maps the safe travel limit of the cone(s), however, I was unaware that that SAM could infer voice coil temperatures. I can worry too much about things sometimes, and I found myself being a little concerned that because SAM can increase how hard the bass drivers are working, then SAM could maybe reduce the design life of the speakers. However, if SAM is keeping a metaphorical eye on both cone travel and voice coil temperature, then maybe this works in favour of reliability? Perhaps a case of take a bit by making the drivers work harder, then give a bit back by watching the driver excursion and temperature?
