WCAG2 Q and A about baseline

I've just been reading http://www.w3.org/WAI/intro/wcag20-baseline.php as 
part of my 'do I need to make comments on this' work.  I am totally 
confused by the use of

Example 1 - Baseline is: HTML 4.01 Transitional

If the user agent supports this technology, then the content meets WCAG 2.0 
at the level the author claims.

Now why is this "If the user agent supports this technology"?  What would 
the user agent have to do with whether the content is HTML 4.01 
transitional?  Surely for testable technologies such as HTML 4.01 
transitional, then the process would be submit the content to a validator 
for testing?
