In a situation like this, would you aim for the grass or the hard runway for the final bit of your landing "roll"?
The grass will obviously cause less damage to the wingtip, but if the wingtip digs into the grass (instead of sliding over it) it may put severe strain on the spar in just the wrong direction (horizontal instead of vertical). And if the aircraft yaws through 90 degrees, you are also putting a severe sideways load on the remaining wheel and wheel attachment, which may cause damage there as well.
Obviously being able to walk away is priority number 1, but if you do have time to think about priority 2 (limiting further damage to the airplane)...?
NO attempt to hold off.
I wonder if this was maybe done deliberately. Not just because of the thermal conditions that have been commented on earlier, but because of something else as well. If you do a lowest-speed-possible, fully held-off landing it is relatively hard to 'grease' it on. With just a tad more speed and power, a greaser is easier.
If you happen not to grease it on (and we all know we don't grease it on all the time) and you have one wheel missing, you might not be quick enough, or not have enough aileron authority at low speed, to pick up the wing where the wheel is missing. By keeping a tad more speed and power on, it's easier to pick up the wing with the ailerons and bring things into a stable situation, before you pull the power and try to keep the aircraft under control for as long as you can with aerodynamics only.
One other thing I noted when looking at the video, and which has not been commented on before, is the way the door opened automatically when the aircraft yawed to the left. He clearly made good use of that four hours and remembered to unlatch the door before touching down.
