Ric:
The crown of the hammer would move in a different arc than that of the shank. 
 When the hammer shank is vertical, and the arc it travels in is at it's 
apex, the tip of the hammer is on a downward descent.   Draw a straight line 
between between the tip of the hammer and the hammer center pin.  When that 
line is vertical, the tip of the hammer is moving straight into the string.   
The shank would be tilted back.   Thus, putting the center pin closer to the 
string means that the tip is hitting the string on a more horizontal plane.  
It makes sense.  Maybe it's a question of which arc you want to worry about.
