lucky indeed ...
Given that the main landing gear on the 330 is tilted upwards when the aircraft is airborne, I would hazard a guess that what contacted the soft ground, just before the runway, were the wheels of the rear axle.
When the wheels of the rear axle came in contact with the runway edge, this would have caused a bit of a violent untilting of main gear, slamming the wheels of the front axle on the runway.
Potential to damage the gear interface unit, which can cause the system to think that the aircraft is in the air, making brakes and reverse unavailable, leaving the crew with nothing available to stop the aircraft after the touchdown. Iberia in Quito comes to mind.
