With regards to inertia, I agree.
Regarding Control surfaces I tend to disagree.
As I already stated the AP disconneting will not so much be the factor here.
The AP makes requests to the FCPC's like a human pilot would do.
In normal law the AP will ask for a roll or pitch demand and the FCPC will provide the 'implementation'.
Therefore Control Surface deflection will depend on FCPC and not directly on AP.
If they had still Normal Law after AP disconnect this would have assured wings level.
It is the reversion to Roll Direct Law that will dictate what the Control Surfaces will do.
As in Direct Law the position of the control surfaces is directly proportional to stick position it is reasonable to conclude that in the given scenario the ailerons would have moved to neutral after change to Alt2.
