The game isn't really played (it's a forfeit with a 25 - 0 result), there's just processing required for the training minutes. The idea is to not punish the active team by giving them training minutes (full minutes in fact if you divide them "equally"), but to not make it easier to manage minutes due to WOs by not allowing a player to get full 48 minutes.
Btw, your previous WO game
(15503926) is more interesting. Your C received 50 minutes in total. I'm no expert on WO games, but I haven't seen that before. How is that possible? We may have a bug here after all.
