True with regards to the flaps out of zero, but having 3B in auto and extending the gear at 250 might cause a gear disagree. Is it a big deal? Not really if the gear still comes down. But to avoid that message and aural you can select 3B to on before extending the gear. Now since ASA always has 3B on it's a moot point.
