Nope, the pink pad counts as one interface, and the gel another interface. Scrape off the pink pad, or don't use any gel.
Any interface will be the limiting factor of your cooling potential. That is, if you have to 'join' two pieces together (preferably, with a gel of some sort), the conductivity of the gel is going to be your major problem. Aluminium conducts heat around 30 times better than arctic silver. About the only time it pays to have more than one interface is if you are cooling with a REALLY large differential, like water/freon/peltier.
