Odd, I have always thought the now standard arrangement was perfectly logical. You pull on the cable to move to a bigger cog/rig with either derailer, aka you always pull on the lever to force the chain uphill. If you grasp how gears work, then what going to a bigger or smaller cog/ring is going to do to your mechanical advantage is perfectly logical too. Always made perfect sense to me.
