The FDIC limit comes into play when there are no underlying assets to distribute to depositors. If the bank has no assets, it's likely all you'll see is $250k.
If there are assets, they can be disposed of, and the depositors with over $250k can receive dividends. The fact that the FDIC is confident that the deposits will be available says to me they were able to successfully sell enough assets to ensure liquidity for whoever took over the deposits.
This isn't a "government two-off to make ALL depositors whole". This is how these bank failures happen.
