Pulling works the upper chest, pushing the lower, in exactly the same way incline/decline bench presses do...
It's off topic, really, for this thread, but the difference in angle between incline or decline presses doesn't reverse the involvement of the chest muscles. The chest muscles contract when you bring your arms
together in front of you - even if you alter the angle. To open your arms and pull them apart when they're in front of you, involves muscles to the rear of your shoulders (that contract to pull your arms apart when in that plane). Presses, be they decline or incline involve the chest because either involves bringing your arms
together in front of you against the resistance of the weight (and in fairness, require significant involvement of the triceps too). In general, pressing movements in front of you, work chest (and triceps, possibly the front of your shoulders), rowing movements (PULLING towards your trunk) muscles to the rear of your torso (and biceps) - (conveniently ignoring exercises in the vertical plane, like shoulder presses, and upright rows).
