Something is off with the specified directions:

> The sun keeps a position relative to the camera and thus the shadows always fall from left to right:

The video shows shadows fall from right to left.

> One can get into the unfortunate situation where the camera is positioned so that the sun casts shadows behind the camera.

The video shows no shadows because they are behind the things that are casting the shadow. There would be no shadows behind the camera.

Is this seemingly reversed notion of "casting" common?

Interesting how you are absolutely right but I didn't notice it at all. I understood exactly what they were telling me even though the description that I was reading was completely wrong.

The fact that I found the animations descriptive and very pretty to look at is probably to thank for that.

I think the author is German (inferred from the TLD), so that might just be the language barrier.

I'm also german. Thats likely not it, german "Schatten werfen" works as the english "cast a shadow".

It also sounds weird to native speakers. Probably just a semantic typo.
