Just to clarify, miles are just another name for points. I've never seen a card that says that you can travel the amount of miles you have for free or anything...
Right, "miles" is probably a hangover (or a deception!) from the days you could only earn points by actually flying. Then you would get X points for flying X miles, but even then there would be exceptions, such as earning 1.5 miles per mile if you fly in a higher class or have a higher status etc. But the 1 mile per mile was always for earning, not for redemption.
