That's because Airbus is flight path stable so the computer resists any pitch that is not coming from the stick. So whether thrust couple or speed increase/decrease the aircraft maintains 1g path. However direct law that's not the case because it degrades to conventional speed stable. That's why in direct law manual thrust is recommended.
