I've seen this behavior as well, but only from the cvs end-user side.

I only have cvs access to one project (MySite) but have 3 commits filed for the Content Recommendation Engine. 

http://drupal.org/user/20975
http://drupal.org/project/cre
http://drupal.org/project/mysite

I don't even checkout modules outside of the MySite directory path, so I know that I didn't commit to CRE. 

I mentioned it to Scott Reynolds (the CRE maintainer) via email and assumed he would file a bug report.
