Hard to explain in writing. That is why I broke it down in to 1, 2a, 2b and 3 to explain. Which part is contradiction ? If you talk in terms of steps you will get confused. It is better to talk in terms of weight transfers and directions. But that makes it very long to write. A very simple explanation would be: you should already be in contra body position before you begin the step where she moves forward to your right. That is simply put when you transfer your weight back on your right foot is the time you should begin to turn right for contra body motion. Your weight transfer on the right foot happens as you transfer the weight from the ball to the heel.
