Pinkpink,
ya, I read about that. Starfruit mentioned that just now also. Her case was cos one of the sac didn't develop normally so they got to remove. It don't pose as much danger to the other one compared to those already developed foetus. Cos that time Reyden was growing much faster than Reyes and gynae did tell us if there's a case of twin-twin transfusion, we'll have to sacrifice one else they'll continue to "fight" and both won't survive. But even if to sacrifice one, the process of removing one will pose high danger to the other one too. Luckily it wasn't that condition.
