As others have pointed out, it sounds like this article only counts the number of GOVERNMENT jobs that were saved/created by the stimulus. It does not consider the number for PRIVATE SECTOR jobs that may have been saved/created.
The Los Angeles controller who did the audit is just doing his job by limiting the scope of his report to government jobs. It is what it is. But you can’t really draw any conclusions about the overall effectiveness of the stimulus based on that report.
