I couldn't find any discussion of the direction the blur, um, spreads in the spec.  It seems like it should be there.

http://dev.w3.org/csswg/css3-background/#the-box-shadow


# The third length is a blur radius. Negative values are not allowed.
# If it is 0, the shadow is sharp, otherwise the larger the value,
# the more the shadow is blurred. The exact algorithm is not specified.

These are the only two references to "blur" that I see in the spec.


Additional note:
Can we use a word other than "sharp" in this quote?  "The shadow is sharp" could easily be confused with "sharp corners".
