This is (technically) true. The airline expects you to be on the flight since you've checked in. You can print boarding passes again at the kiosks or agent at the check in desk. Although you can do this 29 minutes before the flight, it's a pretty bad idea at any medium or large airport since you will need to clear security and get to your flight in less than 15 minutes after that.
