as a useful reference point my local company (London Midland) have always explained the terms of group save to passengers.
If i buy from the guard on the Marston Vale line he will always explain you must travel together and if i buy form the booking office at Bletchely or MK they always explain you must travel together or the ticket is invalid.
Perhaps that would be sensible best practice for others to follow.
I agree. It's not particularly difficult to explain & should definitely be done without exception.
