The aircraft trying to maintain the alpha lock zoomed up past incoming A340. To accelerate past Alpha lock it needs to be broken by pushing forward.
I’m not suggesting that someone should sit there and expect the aircraft to fly itself out of the situation, but taking 10 seconds or so to evaluate the problem will not make things worse. If the aircraft climbs at 200fpm it doesn’t hurt anyone.

If the AoA continues to increase (increasing tailwind for example) then the aircraft will descend if it approaches the critical AoA. Flying around in alpha protection is not the best thing to do, but it is not intrinsically unsafe - GPWS, TCAS, windshear can all see the pilot make a deliberate decision to enter alpha prot.
