If you loose everything and have to restore from cold backup (BTW, why would you *have to* restore from cold backup, you could recover from hot backup as well), why would your previous hot backups be invalidated? They are still perfectly valid, no matter if you had to open your database with RESETLOGS. You still can recover to any point in time, both prior to resetlogs (in which case your starting backup would be any hot backup taken prior to RESETLOGS) and after it (in which case you would use any backup taken after the RESETLOGS).
