That is the ability of 5DM2... the ability to create really thin DOFs... so as to be able to isolate pimary subjects from the distracting backgrounds. It also depends on the lens used on the 5DM2, some lenses have softer border resolutions (less sharp).
In essence, the above clearly shows the power of DSLRs. To the laymen (people who have no idea about photography and DOF) would think PnS wins above because they get everything "in focus" (due to smaller aperture as well)... But if you stop down aperture on the lens on 5DM2, the image would probably be even sharper than the compact. My guess is, the picture from the 5DM2 was shot with the lens' aperture wide open.
