If I'm understanding correctly, the multi-camera matches are the ones that are usually shot by BBC for MOTD, and also get shown live internationally.
So all BBC is doing extra to that is adding some graphics in Salford (presumably) to show live on iPlayer.
BT were taking the international presentation for these matches last weekend, as they did for the extra Friday match in R4 last season.

Given all games are expected to be multi-camera in R3 (as they have been the last two seasons), with international coverage... I suppose there's a chance that BT could show all 32 matches (minus BBC TV picks) on their numerous red button channels.
