It sounds to me like this: Somebody clicks-through an AdWords ad and lands on an advertisers page where the advertiser has put the remarketers code.
The users decides they don't like it for whatever reason and they click BACK to go back to Google's search results and click on an organic listing (not an AdWords ad). If the organic result is displaying AdSense on their page, the visitor may be shown the same ad in the AdSense block that they originally clicked on.
Sounds like a good idea based on the theory that it takes 7 times of seeing an offer before most people will buy.
