Sloppy example. I messed up the timing and didn't get optimal height, but it's still higher than a normal super jump even with the mistakes.
During the counter attack animation you are still considered grounded, thus retain all of your jumps. Simple Perform the Light Sword counterattack move and at the peak of the jump perform a regular SDJ as though you were grounded. Allows you to get an extra jumps worth of height.
