I've been dancing Lindy Hop for years and have always taught my Follows, for the Open Swingout, that it starts with two forward steps/swivels. Recently, I was introduced to the concept of having the Follow start with a rock step which isn't foreign to me, but feels counterproductive and rushes the Swingout.

My question: What's a good way to explain to my students that the Follow can be lead into an Open Swingout by starting with a rock step, and how can they feel the distinction between a rock step and a draw step?
