This is a bit of an over-simplification. Outside of per-dir and PT
your substitution is generally treated as a filesystem path.
As a convenience, when the top-level directory of your substitution
doesn't exist in the filesystem mod_rewrite prefixes the entire thing
with the current DocumentRoot on its way out. This impacts rewriting
to e.g. htdocs/{etc,lib,usr,home,var}, tilde-expansion, or other
mappers like mod_alias (bringing us back to PT). This is why you're
able to break out of your DocumentRoot and Aliases with the
substitution (and adding the corresponding <Directory>.... Allow ...
block)
It's trickier with the PT flag (or per-dir, where PT is implicit), but
I think it is fair to say that it's generally treated as a URL in that
context.
