There are 3 balls in this video. All the balls have the same Key Frames going from +5 Y to 1 Y and 1X to -3X, except the Green one is offset 1 unit to the right in the X axis. The Blue Ball is totally made of Spline Curves and following a circler pattern around its orbit. The Red Ball is totally Linear and follows a Baseball Diamond pattern. The Green Ball changes. The first two orbits it is Spline so follows the Blue Ball. The next two orbits are Spline Broke at each Key Frame so track with the Red Ball. The last two orbits every other Key Frame is Spline Broke so is Linear on the lower half of the Key Frame and Spline Curved on the Upper Half of the Key Frame.
