PS - from the video it looks like he misjudged the approach to me.
The first field was bigger and I think he was aiming for it but overshot.
It certainly looks like he collected the wall with his main gear.

Doubt I would do any better in a YAK, but I did wonder why he did not
use sideslip to increase the descent angle. I expect it is that power
pilots, especially those used to the output of a M14P get totally
focussed on stretching the glide when the engine goes out. The thought
process that comes naturally to a glider pilot in terms of managing
energy to get to a landing point is perhaps not intuitive to someone
used to using only one control to achieve this?

So it looks like he arrived at the field with more energy than he expected.
