As far as I can tell from that section this is more about show-and-tell. There's a difference between demonstrating something to teach it (mimicry) and using language to teach it (explanation).

If I tell you that you can put a stick in a certain tree and get honey out, that's different from me bringing you to that tree, putting a stick in it and showing you the honey (while being swarmed by angry bees but I digress).
