after your very thoughtful and helpful posts, I'm nevertheless still unclear about the bottom line as you see it.
"to maintain 60 deg AoA you need a lot of UP elevator, which takes the THS away from stall"...
..."ND moment can be obtained by reducing the up elevator just as well as applying down - just a different starting point".
do you consider, on an aerodynamic basis, that the A330 is actually likely to be recoverable from even a ~60-degree AoA magnitude of stall upset, given some other set of control inputs [i.e. besides maintaining max NU on the SS until altitude is exhausted]?
