How politicians think:
Oh, hold on, the Federal Reserve and Treasury Secretary can’t authorize these funds unless “there is at least a 99 percent likelihood that all funds and interest will be paid back.”
This means they were responsible, and can not be blamed if things go badly. Something tells me that the document probably does not go into the methodology for determining 99% likelihood of repayment.

This sounds like serious business. Probably getting ready for continuing bank insolvencies, and the commercial real estate crash.
