I remember about half way through the X factor realising that they look totally different. Same with Samanda in BB - at first they looked very similar but after a while, it's quite clear that they're far from "identical". TRULY identical twins are really rare. There were full on identical twin girls the year below me at school (as in not even a blemish or freckle to identify them), they ended up getting drastically different haircuts because they were so sick of people, even their close friends, not being able to tell them apart
