We're talking about how the system is likely to behave in extremis based on the information we have - to be certain we'd need to have an Airbus insider to spell it out.
But in the same breath, a pilot didn't have to understand the inner workings of the artificial feel system in older aircraft to be able to fly the things. As you've pointed out, all this technical back-and-forth is rendered somewhat moot by the fact that the initiating event was sustained and repeated control inputs which were thoroughly inappropriate for the conditions.
As to your other point, the fact that there are only 6 control laws in the A320 causes me to question your source.
