Contradictory prunsrv --StartMethod documentation

The Procrun documentation at http://commons.apache.org/proper/commons-daemon/procrun.html contradicts itself in describing Prunsrv's --StartMethod parameter. In the table of parameters, there is a note that the start method shouldn't return until the stop method is called, but the section headed "Using Procrun in jvm mode" contains the following sentence:

Note that the method handling service start should create and start a separate thread to carry out the processing, and then return.

I don't see how it could be both at once, so which is correct?
