Canon's messed up DOF calculator?

DOF calculator: http://cpn.canon-europe.com/content/technical/depth_of_field_calculator.do

So when I switch between the 5D Mark II and the 40D it tells me the DOF is narrower on the 40D than the 5D Mark II? What's up with this? Shouldn't the DOF be narrower for the full frame camera? The 40D has a 1.5x crop factor I believe.

Never mind, my stupidity...I put in 35mm lens on both cameras but the FOV of the full frame camera is of course much wider so I needed to put a 52mm on the 5dMk2. Sure enough 1 stop difference.
