There is an attempt to cover as much windshield as possible. A minor variation either way can result in overspray, but that is easily fixed by adjusting them. Also, as soon as the wipers come on, the fluid is going to go flying in all directions, up, over, out, everywhere, that's inevitable. From the perspective of the person in the car behind, it looks as if the fluid went everywhere except on the windshield.
