Its a simple time over distance thing. If you have a wind, doesn't matter the direction, blowing on your range and the wind closest to the muzzle blows the projectile off course, then that projectile will have more time and distance to continue off course than it does if the wind blows it off course at the midpoint of its distance to the target. That same wind, at the midway point, can not correct the projectiles off course condition due to a lack of time of flight and distance to the target.
