It is physics which work on any ball with aproper release. On a good shot with some revs (does not need to be much) you should recognize an increase in revolutions after the ball went through its breakpoint - the ball might even speed up on the back end.
This is created when two forces, the roll and your release revs, work into the same direction after the breakpoint. Before, your axis tilt simply "divides" the ball's forward movement and the sideways release revolutions, the oil and a slick ball surface help keeping up energy for later.
After the breakpoint has been passed, both forces add up and the ball "revs up". Lower RGs will enhance this impression, but it also depends on lane conditions and surface prep. Also, colorful balls or high contrats inserts will improve the recognition of this effect.
Hope this helps.
