Someone who flew this exact airframe wrote that this plane "likes to float when empty, so if you’re not firm with putting it down, especially with those winds, it’ll just keep floating in ground effect."

I'm not a pilot but from my understanding there's a lot of failsafes to ensure things that slow the plane down only trigger when the plane is actually on the ground. Considering that the left gear touched down at 0:19 and pilot called for TOGA at 0:15 they didn't stand a chance.
