[CSS21] Unclear wording in section 10.6.2, 10.3.2

In 10.6.2, the second paragraph says:

   If 'height' has a computed value of 'auto' and 'width' also has a
   computed value of 'auto', the element's intrinsic height is the used
   value of 'height', it has one.

In 10.3.2, the second paragraph says:

   If 'width' has a computed value of 'auto' and 'height' also has a
   computed value of 'auto', the element's intrinsic width is the used
   value of 'width', if it has one.

I assume 10.6.2 is supposed to have the "if"?  Even so, it's not so clear what 
"one" refers to here...  Given where the clause comes, it would seem to refer to 
the "used value", which is not likely to be the intent.
