The basket is different and designed to work with the pin. there are two layers to the bottom of the basket, the one that you can see in the pic and one underneath with a single hole, the pin ensures that the coffee coming out of the single hole does so at a standard rate/pressure, this increases the pressure and means that even an idiot can get a half decent coffee with crema. It does however, as far as I understand it make it almost impossible to make a really good shot. I think Bombcup mentioned advised people to get rid of them a while a go.
