Gear numbering is not consistent.
Neither, now, is shifting direction with SRAM twisties. I replaced the set on my wife's bike two years ago. The old set was a mirror left to right and thus worked in opposite directions, like shifters always have, and the left had three positions. The new one was the same basic unit left and right and thus they both got easier or harder in the same direction, and it had about twelve clicks to permit trim.
