I still don't think that's accurate for the 95-97 cars.
For older cars, it's true that you could pull up on the driver's
door lock and this would activate the other locks through a vacuum
system, but it doesn't work that way on the 95-97.

I've seen the little green vacuum tubes that start at the central
locking controller.  They start out under the rear seat and go out,
teeing off every once in a while to head to different places.

Another possible explanation is that the driver's door
lock failed was in such a way as to cause a vacuum leak, and
thus the vacuum pump couldn't unlock the other doors.
It would have to be a miracle leak that fixed itself later.
Maybe condensation in a vacuum line froze, caused the line to
expand and leak?
