1) to 2): The man steps to the left and as he does so he swivels his shoulders (NOT HIS HIPS) to face to the left.
2) to 3): Then he takes a second step to the left and this times swivels his shoulders right round to face to the right - HIPS STAY FACING FORWARDS.
3) to 4): Then he takes a step back to the right and swivels his shoulders to the forwards position again.
4) to 5): Finally, he takes one step forwards - leading with the right foot - with shoulders still facing forwards.
Meanwhile the woman is pivoting on one foot then the other and generally trying to keep up with the man who always seems to rule the roost when Tangoing.
