On the Nikons the EV compensation dial is attached to the ISO dial... so I'll bet it changes the ISO setting. It really doesn't matter which of the 3 values one changes to compensate their exposure as long as one knows how to do EV compensation (either for off-nominal scene exposure "correction" or pushing/pulling purposes) and the effect/impacts.
