If I weren't there, the host unreachable would have the source address of the upstream router, and not my own one. To be truly invisible, you'd need to fake the upstream router's IP address, which is (a) not easy to get hold of, (b) most probably not appreciated by your upstream, and (c) some hosts will completely cease communication with you which is not always the intended behavior.
