I misunderstood your original post. I agree that the accident was the culmination of a series of pretty serious errors. I assume they got a fair amount of retraining before going back to the line.
(As an aside, looking at their ages from the report, they should both be at or near retirement now)
The CA responded to the ECAM by saying "they're set". He seems to have thought that the ECAM was telling him that the levers were not properly seated in the detent, which would explain why he simply moved it down then back into FLEX instead of TOGA.
I only mentioned the size of the other operator to indicate that both crewmwmbers had significant experience in type.
