I hope so. I still don't get the reason for the alternate ending 
Well, it was clearly because they only had a 12 episodes slot on TV - a standard season. Either they'd already written a 15-episode series and couldn't convince the TV channels to let them air the whole thing, or they didn't think they could write it in such a way that they could reach a convenient stopping point in the story within 12 episodes without introducing loads of filler, or really rushing it. So they decided to write a quick TV ending, so that the TV season could finish properly, then carry on their 15-episode series online, so they could tell the story the way they wanted to.
I'm really glad they did too, episodes 13-15 were the best part of the whole series IMO.
