For the old url_rewrite_* interface that is pretty much the case.

The storeur_rewrite_* interface does change the URL which determines
whether two pages are cached/fetched from the same slot.

Just be aware it also makes the URL fetched possibly disagree with any
URLs in the page body or Location: headers, cookies etc. which brings
browser security features, XSS and forwarding loops into the picture of
things to be careful of.
