I would use the identifier device AND any circuit labelings as a guide, even after all the circuits have been identified. What if the circuit breaker controlling the circuit you are working on doesn't disconnect as it should when you flipped it off? What if there is a wiring error (red and black lead become shorted -- now two circuits became one). What if all the outlets in "north bedroom" are on one circuit EXCEPT for one?
As for the identifier device indicating all (or several) circuit breakers are the source for a particular outley, yes, can happen: the wiring for your circuit became entangled with another circuit or two, causing the signal to appear on several circuit breakers.
I use the circuit tracer here as a guide; and yes, there are a couple of circuit breakers which appear to control the same outlet.
