Pretty much, yeah. If they're doors that you can identify with Passive Perception (i.e. just glancing around a room) they're not very secret, are they?
One of the time savers in 4th edition is you are now assumed to be alert and looking for things like traps, tracks, and hidden enemies. It's no longer necessary to state explicitly that you are looking for secret doors in every room and hallway. Passive perception is not just 'glancing around a room' I'd treat a time when PCs are explicitly not on alert as taking a 1 on a perception roll.
