Confiture
Those are not extra measures, they're only different. As per CVR the pilot did not elect to permanently inhibit Alpha-Floor, but only temporarily by inhibition upon activation. Doing so is only possible if AoA has already reached 15 degrees, but at the time TOGA was manually applied by the pilot, the AoA had not yet reached such angle.
Too fast he was.
OK, so in your view he intended to cancel any thrust increase from Alpha-Floor if it triggered but this intention was overtaken by events when he applied TOGA thrust too early (for Alpha-Floor to trigger that is).
This would seem to make any consideration of the part that Alpha-Floor might play in this affair totally irrelevant.
That take us back to the conclusion that he intended to make this demonstration in manual flight, taking on his own shoulders the responsibility for energy management and relying entirely on his own experience, skill and judgement.
