If you find that disturbing, you must be perfect I think you will find most A320 series pilots forgot this quite a lot of the time...
Guilty as charged. At one point I thought they may be trying to be clever, by ignoring Operational Procedures to avoid the slight idle thrust increase, now I'm not so sure. Could the fact that they were trying to land the aircraft with the A/Th increasing on #2, contribute to some mishandling of the thrust levers on touchdown?
Not trying to be an investigator, just enjoying the discussion as seen from the different points of view.
