In crude terms, the lab measurements establish a model of the speakers performance. This virtual model is then reversed to make the SAM corrections. So SAM knows that if it puts x amount of power (volts x amps) into a speaker, this will result in x amount of cone movement, and x amount of heat into the voice coils. So if you think of SAM as being a virtual / digital model of the speaker, then yes, the Delialet's little brain can handle all this in real time. All very clever stuff! Obviously SAM is not taking any actual measurements, so if there is a difference between the actual speaker they had in the lab, and the one you have in your home, then this could be problematic! I presume that they have built in a reasonable safety margin to allow for production variations of a mass produced speaker? Or at least I hope they have!
