There's not 2 pieces for elemental and 2 pieces for resto, though. Most slots have 2 choices of int mail (shared between both) with some slots having 1 choice, and 1 slot having 3 choices.
Elemental uses spirit so blizzard doesn't have to itemize resto gear and elemental gear independently. They basically itemize one type of gear, int mail and call it good. Often giving choices on some slots for spirit or not so shamans don't have a silly amount of hit.
