Sasuke copied Shadow of the Dancing Leaf. A move stated to require intense training to do correctly and Sasuke did it perfectly in the first try.

That particlular quote you are referencing has to do with reaction not copying. As again Sasuke couldnt react to Lee and his Dancing Shadow but mimiced it.

Also Madara was able to use perfect wood clones evem though had zero experience with.
