Yes.

Well, if the doc tried to list all the things people might try that
wouldn't work, it would get awfully long. Nevertheless, if you look at
<http://httpd.apache.org/docs/2.2/en/stopping.html> you'll see this:

 Multiple running instances of rotatelogs attempting to rotate the
 same logfiles at the same time may destroy each other's logfiles.
