"Does he say rise at the end of step one meaning on two we are already as high as we are going to be on step three."
Rise at the end of step one does not mean that you will reach your full height at this point, as reviewing any video would show. Instead, it means that the rising actions in the feet are complete - however, the body will continue to gain altitude as the legs close during step two, reaching its peak altitude only at the end of step two, and then starting gradually downwards via leg division even before the formal foot lowering occurs at the end of step three.
Once again, you assume a meaning that not only isn't in the text, but GROSSLY CONTRADICTS the actual dancing as done by everyone of any skill whatsoever.
