It is a silver level technique, and I have heard it referred to as "brush steps" on occasion. Not sure if that is the best and most accurate way to describe it, but it does help you visualize a little bit what you are actually doing when you go into continuity steps, or when it becomes a little more complex, we call it "continuity styling." Look at it as your very first encounter, or baby steps, into the stratosphere in which Fred Astaire and all great ballroom dancers ply their trade.
