Definately incorrect on both counts. That would severely impact revenue losing full BC fares. The whole upgrade idea is based on unsold BC seats.
Though Elites and Corp booking *full* coach fares do get automatic upgrades to BC at time of booking. So make sure you book using your account.
The Elite using credits inside T-48 upgrade is a holdover from the autoupgrade they ran during the holidays awhile ago.
