UC G Ticket: Clubhouse access for guests on different flight

Hi everyone
I've booked two reward flights in UC to NRT for next month. We'll be arriving at LHR with some friends who are travelling VS Economy to SFO and we'd like to sign them in to the clubhouse.
I was just browsing the Fare Codes on the toolbox on this site and noticed that for G class tickets it states 'A ticket in this class will allow you to utilise the Clubhouse/Shared lounge on your journey for you and one guest flying with you'. All the other UC far codes say you can sign in your guest 'providing they are on a Virgin ticketed flight on the same day'.
The rule suggests that for the G class ticket your guests have to be on the same flight as you.
When I contacted VS they first said we wouldn't be able to sign in our guests, then they said they'd made a mistake and that we could. They seemed a bit uncertain, so to avoid potential embarrassment at the clubhouse entrance, does anyone know for sure if we'll be able to sign them in?
Sorry if this has been answered before, but I couldn't find any clarification on it. Thanks in advance
