Their explanation is wrong. This discussion was had last time. Unless the fox understands the idea of distance the triangles can't be dense. If it understands distance the idea falls apart. One explanation might be, if the fox stops and looks around after 100 triangles or some sort of signal. When it looks around, it's more likely to be in a treasure zone. But the fox will not go toward high density triangles, because it doesn't understand density.
