Dancing Leaf Shadow is the part where the user floats behind the airborn enemy. He copied it flawlessly. Guy even remarks how impressive it is that he was able to use it as well he did. Even when fighting the curse mark he had Dancing Leaf Shadow down. Chapter 68

Regardless of how OP Madara is he did it. He copied a technique perfectly without practice or without ever using wood release beforehand.
