It's related to the posture that you can see from olympic weightlifters. When the weight is supported above the head you must look squarely front. If they look up the same weight cannot be supported. At full extension for impact during serve unless the head is already turned toward the target the extended arm loses its ability to achieve high swingspeed at full extension. This is different from rotational swing of GS where it's possible (but not a requirement) to fix the eyes for the ball at contact.
