Why would they though? They need to get that money from various banks, if they can't get them then they're SOL, right? Goldman hasn't offered any guarantees before, have they? Studies are saying its going to take 30 years to set a net gain, so they could have issues with money if suddenly they need it. That's with two teams as well, if it was one team its 40+ years, the return isn't actually all that much for the first few decades, because they have to pay back all the various banks that they borrowed from. They're not just borrowing from Goldman Sachs, they're borrowing from a bunch of different banks that Goldman Sachs is setting up. At least that's how they've done it before and from what I read a whole ago were doing again.
