You would not be using both an all-flying tailplane and elevator for pitch changes simultaneously.
But if we compare the effects of the two types of control surafce we could argue that they both operate in the same way.
Pulling the stick back will,
move the trailing edge of the elevator upwards so that the elevator is in a leading edge down attitude.
Or
move the trailing edge of the all-flying tailpane up so that the tailplane is in a leading edge down attitude.
