That's a really hard to read article which is summarizing a couple of tweets.
Spooked foxes aim to be 100 "triangles" away from the player on a pathfinding mesh. Where are they likely to run into the 100th triangle? In a place with a lot of pathing points, so it'll often lead you to a camp or something interesting.

In real life, animals might also be seeking out that 100th triangle. In low density areas like fields they are super exposed to predators and the elements so if chased or watched, they'll go to places with complexity and resources. I think this is a very amusing and interesting parallel between the virtual worlds we build and the real one nature built.
