they looks like they are reversed but they give the corect shadow and that what you see are not shadows, I know what you mean I saw the topic last time but this is only illusion of our eyes and not for real. if you use displacement map you have to use diffiuse maps to make this works correct. here some color fur, not textures oly the same maps as above with some color.. the fur looks much more real but after reduce of the size it lost the best effect..
