You are always at the same distance from the rack, no matter what height you're trying to get. (That's another advantage of telescoping designs in general; you can always be in the "safe" scoring zone. Sometimes, your arm pushes you out into the "get pushed around" zone.)

The advantage was for the top row, you didn't have to turn around. It allowed a forward-back motion without ever having to turn around. They were a great complement to an elevator who would stay and maneuver int he zone scoring, while the over the top arm would go far for tubes.
