Why would it be any different on a domestic?
The point I think is simply that BA don't over cater. So there is no 'spare' catering to cover upgrades. Flights are return catered (i.e. loaded in London) so if upgrades / bookings are last minute no time to get top up catering and BA won't load catering down-route. So the risk is if everyone accepts the meal there won't be any spare for the upgrades.
