It only works that way if no current is drawn. If current is drawn, then the resistance of the windings consumes some of the voltage. This is why PSUD wants to know both the open-circuit (no load) voltages AND the winding resistances. Just another one of those things that are not obvious until they are. :^)
Incidentally, it works the same with audio output transformers.
