   I studied that at the university (signal processing). An industry   
   scientist thought us the double mean trick (and its frequency domain   
   correspondance). Using the same filter on both series makes an eventual   
   "distortion" the same for the two series. Actually, the whole thing   
   compares the desaisonnalized monthly variations of both series.   
   If you still have a doubt, the wood for trees graphing tool has a   
   fourrier transform tool. The final result is the same.
