Well, I think is a little bit complicated.

I guess the whole thing works like this (not 100% sure):

- - if /usr/bin/nepomukserver exist, when is started.

- - if /usr/bin/nepomukserver is missing, then a process (a thread?) is 
  created by /usr/bin/kdeinit4 (you can change the process name once the 
  program has been started by modifying argv[0] or you can use 
  prctl(PR_SET_NAME, ...) for a thread - sorry but I'm not a kde developer 
  so this is my best guess).

How can you test this:

1. Make sure /usr/bin/nepomukserver exist.

2. Logout, login.

3. In a terminal run "pstree -acgp"
   Notice the nepomukserver's PIDs.

4. ls -l /proc/<PID>/exe
   (replace <PID> with the actual PID.
   It should be a link to /usr/bin/nepomukserver

5. Rename /usr/bin/nepomukserver.

Repeat step 2 to 4.
In step 4 the link should point now to /usr/bin/kdeinit4.
