More or less. The seam orientation for both third and first base sides (for a range of gyro axes) creates a pressure distribution which moves the ball to the third base side. In Figure 2 you can see the separation point on third base side, while it moves around, on average is more towards the second base side than the (averaged) separation point on the first base side of the ball. The resulting pressure distribution because of this will provide a force in the third base direction.Are you saying that the seam orientation on the third base side effectively creates and air foil so the pressure differential similar to the lift on an airplane wing moves the ball toward third base? The airflow diagram on Figure 3 vaguely looks like this.
There is nothing special about an airfoil design other than the shape is such that one tries to provide maximum lift and minimum drag for the flows the airplane is designed to encounter (airfoils for fighter jets will be different than passenger jets, etc). Anything put in a flow will have a resulting set of forces.
