What's not to understand? Microsoft is colecting search phrases from searches people make though the IE search box. Then they are tying that data to the next page people click to after the search. Google intentionally polluted their data using odd phrases and asked users to click on their bogus results. Given that the only data bing would have for those strange phrases is polluted crap from Googlers it's not surprising that their engine that's using user supplied data would attempt to return the only match it can find.
