Provided the alleged incident is true, does the A320 FCOM actually recommend doing high-g turns, or touch and goes to release any abnormal L/G?
On my 'Bus, you basically try the gravity extension twice and then proceed to the LDG WITH ABNORMAL L/G checklist and land with what you've got.
The chances of causing further grief to the airframe/components/L/G with high v/s touchdowns should also be considered.
In any case, well done to the crew. We all know the "Any landing you walk away from is...etc." adage... :-) but a little bit of constructive critique with the benefit of hindsight does no harm!
