Why is windup different?

5.7 TIME OF PITCH
The time of pitch is defined as the moment the pitcher's movements commit him to deliver the
ball to the batter.

In a windup position, this is defined as the moment the pitcher begins the natural movement
associated with his delivery of the ball to the batter (i.e., the start of his windup or delivery).

From a set position, this is defined as the moment the pitcher begins the natural movement
associated with his delivery of the ball after the pitcher has come set with both hands together
in front of his body.

If the motion is associated with his delivery it is the start.
