Actually that was my first instinct, until I realized that if  
"center" was to be equivalent to "left" , "right", "top", or  
"bottom", then its namestake value should be 0. In other words,  
"bottom:0" means the bottom edge goes all all the way to the bottom  
of its container, "left:0" means the left edge goes all the way to  
the left of its container, so it makes sense from that viewpoint for  
"center:0" to mean the center is aligned with the center of its  
container.

But I can see your point too.
