I think you're misinterpreting what it says, or at least what it
intended to say (since I think there's a section missing... though
I'm having a bit of trouble reading the spec due to the obsoletion

describes the value of 'content' as:

  [ [ <uri> | icon ] ‘,’ ]* [ normal | none | inhibit | <content-list> ] 

url() values can appear in two different places in this syntax:
before a "," or inside of <content-list>.  When they appear before a
"," they are treated as a replaced element (as the spec describes).
When they appear inside of <content-list>, they are processed under
the CSS 2.1 model and are not a replaced element.  (This bit is less
clear because some of the subsections under <content-list> appear to
be missing.)

If 'content' contains a single url(), the only way to make the value
fit the grammar is by making that url() part of the <content-list>
production, in which case it is not treated as a replaced element.
