I guess Google News still has to work on their "interpret creative writing" module:

The PowerPoint story is actually a critique on the use of the infamous slideshow software, which cites NASA's technical presentations as an example of Powerpoint misuse. While it shares the same keywords with the other two articles, the NYTimes report is not about NASA's response to the CAIB recommendations - it only starts with approximately the same words. Google News needs to do some more semantic voodoo for these kinds of freak occurences.
