Comment:
If you run pstree you'll find the following line:
    --snip--
     |-kdesktop---kdesktop_lock---kblankscrn.kss
    --/snip--
So I presume kdesktop (which cares about desktop-related things) launches kdesktop_lock which locks the screen, and the latter launches the actual screensaver (here, the blank one).
