A fair point, this applies to at least some of Virgin Media's packages too (see http://allyours.virginmedia.com/html/broadband/wireless.html). Hitting the reset button won't restore the original firmware, to do that you'd need to follow the instructions above again in reverse using a copy of the Virgin firmware.
On the plus side, I've never heard of anyone being asked to return their router, by the time they reach the end of contract they're usually obsolete. Still, it's your call whether you mind breaching the T&Cs of your agreement with Virgin, we only provide instructions, not advice on whether it's a good idea to follow them or not!
