Funny (not) Airbus in normal law is not supposed to be stallable. (Well according to check airmen, who wouldn't believe Mother Nature is a bit quicker than mere computers) So if it somehow ended up in alternate law "again" methinks Airbus need to re-evaluate their design.
Again speculation is futile, but I'm sure other crews would also have been caught out so I believe respect to the crew is called for as they were just doing their job, using their peers skill set that was/is deemed adequit.
