Of course it's a huge victory. I'm just afraid that if some key issues aren't handled to the voters' satisfaction (be it left leaning or right leaning voters) they will be disappointed in this coalition and again turn to pis or other, fringe parties which would give pis more power again. We have seen so often, not only in Germany, how people vote for a party solely because of one single issue and if you have to trade off some of your democratic systems to reach that goal that's a sacrifice they're willing to make.
