You'd have to read what I wrote above that. But I will give an example:

What I am suggesting is that if that if you have, for instance, 4px  
for the blur value of box shadow, then it is a 4px blur on an outer  
shadow, as it is now in Webkit. But if you specify a -4px blur value  
then it would be interpreted as a 4px blur on an inner shadow. So the  
blur is still 4px wide, but the negative sign indicates that it goes  
on the inside and not the outside.
