A high-to-low chop that carves your obliques.
Rotate through your trunk, keep your arms long and let the core drive.
Chopping from shoulder height down to the opposite hip loads your obliques and deep core through a rotational pattern with a downward pull, the kind of force you produce when swinging or throwing. The high pulley means the stack fights you on the pull and again on the controlled return, so both halves of every rep build trunk control, one side at a time. It belongs in any core session that has outgrown planks, especially for athletes who rotate under load.
Essentially, yes, it is the classic high-to-low chop pattern. Set the pulley high, stand side-on and drive the handle down across your body while your trunk does the rotating.
You are pulling with your hands instead of turning your torso. Keep your arms long, soften your grip slightly and think about rotating your ribcage toward the opposite hip.
Let the back foot pivot naturally as your hips turn. Locking both feet flat forces the rotation into your lower back instead of your hips and core.
