Same resources with the same URLs, access with the same request/response pipeline that's just as visible to blockers. If you can change URLs in the bundle, you can change them outside the bundle.
UAs are also completely free to request a resource from the URL rather than the bundle.
If this really did prevent ad blocking no one would expect it to ship. Inside the bundle are the same resources as without a bundle.
