Weiguang, Points are duplicated for the polygons defining the end caps so that a separate normal for the end cap can be specified - it's a common computer graphics technique to get sharp edges where desired. Uncheck the "Capping" property and your source will have 20 points as you probably expected (but no end caps).
If the point duplicating weren't done, the cylinder would look funny at the ends. Try running the Clean filter on the cylinder to see what it would look like. This merges the duplicate points.
