If there are pages on swap, that is because at some point in time those pages where considered "not used", and were written to disk. If those pages are never reused, they stay where they currently are, because it is the most interesting thing to do performace wise. Trying to keep swap=0 could cause some ping-pong effect under some workloads, with heavy access to disk, that are too slow to be accesed more than strictly necessary.
