Neither does an assisted chinup/dip station.
Tons of machines are functionally useless against their freeweight analogue
The assisted chin/dip station is actually very good at getting untrained people ready to actually do their own bodyweight.
Back in my days as a trainer, I would have clients do the assisted chin/dip, but I would also add in negative only chin/dip. Magically, each and every one of them, including the dude who was 100 pounds overweight when we started, was eventually able to do 4-5 reps at each.
