As you put it here, we can assume A/THR is ON. This was not specified in the initial scenario.
Point 4 is of no importance as there is no 'thrust limitation' at
FL390 since climb thrust is nothing short of MCT or TOGA. Nothing to gain to have alpha floor anounciated on the FMA as thrust on the remaining engine is already at its max possible output.
As mentioned earlier, the important point is the alpha prot activation preventing a further AoA increase.
It is still a good scenario to think about.
