As sfeng describes in another comment, the math isn't right, but the concept
does make sense. It doesn't negate what you're saying either though; the 5
point landing is basically a way of distributing the force over as much area
as possible. (You can't accomplish the same thing by just landing on your
side, because the mass of your body isn't evenly distributed across the
surface that would contact the ground.) It does manage to distribute the force
over time a bit too, which is also beneficial, but a less significant effect.

Excellent read. Just a few more pointers from personal experience. When over
water, "pencil" your body, feet first, at the very last second. Molecules of
atmosphere, which are your friend at 120mph, are not so much when they are of
water.

Also the author didn't mention my favorite survivor Juliane Koepcke.

I've never been on the offshore survival course where they teach you how to
jump off an oil platform into the sea and survive, but allegedly they tell you
to cover your mouth firmly with the palm of your hand and pinch your nostrils
closed tight between your thumb and fingers. Apparently when you hit the cold
water your natural reaction is to breath in. Also, you must prevent water
being forced up your nostrils and damaging your brain etc.
