It concludes by directing you to the gravity feed checklist, and the status page showing
CTR TK FEED: MAN ONLY
I suppose the centre tank fuel wouldn't technically be trapped. You'd just have to send it the long way around.
I believe you are mixing up different MSNs here. If You are talking about jet pumps equipped MSNs there is no distinction between center tank empty or not as the fuel will still be fed to the side with the pumps operating (there needs to be a suction in the jet pump created by the wing pumps as you have written above).
