They all have the keyphrase in links that point to the pages, not in links that are on the pages. To check them out you'd need to take one of the listings and get the links that point to it (you'll only be shown PR4 links and higher). Then you'd need to check each of those pages to find any that contain the orginal keyphrase in the anchor text that points to the original page.
In other words, take Google's word for it
