In other words, the derailleur cage rotates to align perfectly with the chain in any given position. This not only improves shifting accuracy and speed, it eliminates the need to "trim" the derailleur to prevent the maddening chain rub that can occur toward the back of the derailleur's cage, regardless of what chainring/cog combination you select.
