Not sure if this will help explain or just confuse more. But when I was new to honing Victor showed me something that helped me to understand.
Take a diner plate and put it on the table. Think of the rim of the plate being the razors edge and the base of the plate being the spine. With one finger push down on the edge of the plate until the edge touches the table. Now rotate the plate with the edge and base staying in contact with the table a 1/4 turn. This is a rolling stroke. The edge and spine stay in contact but move. Then after you get that figured out the next thing is to learn that the point of contact on the edge and spine needs to make an X pattern while moving across the stone.

Id draw a picture all i can draw are stick people.
