LOL mate - it looks quite simply as this.
Thats the caliper wrapped around the pad carrier. As the pads have worn down the caliper has got closer and closer to the pad carrier - making it seem as though they were together.
Now you've fitted new pads the gap has re-emerged.
I might be wrong, i don't think I am - without further pics anyway, but it looks perfectly fine.
I'm guessing your brakes work? lol.
