So, let me see if I have this right. In your camera, you had one card slot set for raw and the other slot set for back up, also raw? And then, did you upload straight from your camera? If so, then this makes perfect sense to me. The 001 would distinguish between two identical files.
Or, did I completely miss something?
On the cards, the filename is the same. When you load them on the computer, either by importing with LR or copying in Windows Explorer, it adds a dash and a single digit to the filename. At least on my computer, it doesn't use leading zeros.
