[css3-background] error in box-shadow examples?

In:

  http://dev.w3.org/csswg/css3-background/

there are some nice figures in Example XXVIII.

The two last examples show the effect of "spread". However, they do
not set the fourth length parameter, which represents "spread":

  box-shadow: 
    rgba(0,0,0,0.4) 
    10px 10px
    10px /* spread */

  box-shadow: 
    rgba(0,0,0,0.4) 
    10px 10px
    10px /* spread */
    inset

I believe the two eaxmples above are missing one length value each.
