I'll try to provide a better example.
This shall be our orginal page:
<!DOCTYPE ...>
<html>
 <head>
 <title>Some article</title>
 <link rel="stylesheet" href="style.css" />
 </head>
 <body>
 <h1>Some article</h1>
 <p>...</p>
 <p>...</p>
 <p>...</p>
 <p style="color:red">
 <strong>Do not</strong> try this at home!
 </p>
 <p>
 Last update:
 <abbr class="page-last-modified" title="20050102">2 Jan 2005</abbr>
 </p>
</body>
</html>
Now we make a cosmetical change.
We add
 p.warning {color: red; }
to style.css and change our HTML file to:
<!DOCTYPE ...>
<html>
 <head>
 <title>Some article</title>
 <link rel="stylesheet" href="style.css" />
 </head>
 <body>
 <h1>Some article</h1>
 <p>...</p>
 <p>...</p>
 <p>...</p>
 <p class="warning"> <!-- <<< -->
 <strong>Do not</strong> try this at home!
 </p>
 <p>
 Last update:
 <abbr class="page-last-modified" title="20050102">2 Jan 2005</abbr>
 </p>
</body>
</html>
Althought we updated the file we did not change the visble content,
i.e: no user would bother the re-read the article because there is
no visible change.
Therfore we didn't change the date of <abbr class="page-last-modified" ...
I hope that the above example brings some clarity.
Additionaly this microformat has the benefit that it can
be used to denote the last modifcation of an entry/item, e.g:
<div class="some-microformat-container">
Content ...
<p class="fineprint">Last updated:
<abbr class="last-modified" title="...">...</abbr>
</p>
</div>
