That's not actually the point of this article. Many many lenders are not on good terms with their counterparties. Distressed debt and bankruptcy exist. And yet, I've never heard of another story of a bank accidentally wiring nearly a billion dollars to creditors.

The amount is unusually large for this type of mistake, making it newsworthy, but it isn't particularly unique. I have personally seen a couple cases of various mistakes in banking (both on customer and bank's side) causing accidental repayment of debt that otherwise would be unrecoverable as the payer became insolvent. Mistakes happen. Human processes and technical processes can help make a bit less mistakes, UX is part of that.
