From that page:

<blockquote>The use of RewriteRule to perform this task may be appropriate if there are other RewriteRule directives in the same scope. This is because, when there are Redirect and RewriteRule directives in the same scope, the RewriteRule directives will run first, regardless of the order of appearance in the configuration file.</blockquote>

The rest of that doc is interesting. I agree that these directives are simpler and more suited to the task, but the above does seem like it could result in unexpected issues.
