This will allow the spindle to reverse very quickly.
I was doing some tapping with a tapping head at 1200 RPM recently, and the spiral-flute taps performed MUCH better at that speed (in aluminum, 4-40 thread) than at lower speeds. I don't have a spindle encoder on my machine, yet, so i still have to use the tapping head to do the reversing.
