The spec has a diagram that illustrates how document.write() is 
integrated with the parsing by injecting markup back into the input 
stream [1].

This test case illustrates how document.write() can change the parsing:

<!DOCTYPE html>
<title>document.write()</title>
<body>
<div>
   <script>
     document.write("<\/div>");
   </script>
   <p>Is this paragraph within the div or not?
</div>

When script is enabled, the p is a sibling of the div and the </div> at 
the end will generate a parsing error.  When script is disabled, the p 
is a child of the div and there is no parsing error.
