The only thing I can figure, and if it were the case, they could have wrote it a lot clearer is : They want the full $25 million (22.5 after fees), and Gabriel probably showed up with something worth $25 million for collateral.
The bank isn't going to offer 100% LTV on that collateral, so Gabriel had to shake the bushes for some more.
Believe me, I know this is a stretch. But I'm not Miss Cleo.
