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.

A naive question: how can a cylinder with resolution=10 have 40
points?
Best,
