If the typical stride length for the pitcher's fastball is around 80-90% of pitcher's height, then the pitcher would need to reduce stride by 10-20%. By doing so, the pitcher eliminates the possibility of tipping off the pitch.
It confuses the batter by giving the illusion that the ball is faster than it actually is, because of the greater difference between the start speed and end speed.
