It says it all right there about "automatic extensions." I was talking to my CA during my trip here at PSA, and it is a common belief that extensions are automatic here. Absolutely not true and here's the document that says as much. Spread the good word.
At 9e, our FOM says we automatically accept the 30 minute extension when we sign the release. Seems to match what that letter says.
