How did you determine the pictures he took have a high dynamic range?

I looked at those pictures and had the opposite feeling.

I was surprised how bad they are from a pure quality aspect.

I assume the jpeg and scanning is a very hard limiting factor.

I can get a lot of range when shooting raw with my canon 80d.

The analog pictures are reasonably contrasty, but they do preserve highlights in a very nice way.

If you look at the top picture in the post then I'd have more dynamic range with my DSLR for most of that picture, but the parts in direct sunlight would be completely clipped instead.
