The more commonly seen case (a la Waqar) is true reverse swing, as it goes away from the seam direction. The direction of contrast swing depends on the speed. I do enough physics at my day job so well leave those details be, and focus on interesting results. Using a properly conditioned old ball, any bowler can now swing the ball both ways, just by flipping the shiny side. A wet ball is much harder to swing in the air. For a new ball, the shiny side will travel more because its smooth. This is also the same direction as the shiny side. It is said that the old ball with one shiny and one rough side will always go towards the shiny side. Their default release is for an outswinger, and their default reverse direction goes into the right-hander. They did a comprehensive analysis of the motion of new and old SG balls tilted at different angles, measuring the swing force, modelling the flow of air around the ball, and computing the trajectory of a ball as it goes down the pitch. It isn't drift because if I turn the ball around it goes the other way and scrambled seam there isn't any of this movement.
