I run a swing screen read opposite of the counter screen that is set up by a ghost/orbit motion from the opposite side. The swing would be a pre-snap read for the QB where he will throw the swing if the defense doesn't bump/push/rotate to the swing. Post snap he is simply going to read the end and we assume that the motion will hold the backers for half a step and give us better angles when pulling. This seems like a similar situation where the QB is reading pre-snap adjustments by the defense into a post-snap counter-read.
