It looks to me like top is using a different definition of swap. If you compare you see that SWAP shows the difference between VIRT and RES almost exactly. However, if there is no or almost no swap usage how can there be a difference? Only explanation: it shows what *could* be swapped immediately without affecting current activity. Have you tried making it heavily swap and then checked if you see a difference (whichever)? Theoretically, it shouldn't make a difference as it doesn't seem to differentiate between "swapped" and "really swapped".
