According to Matador, the message from Google and YouTube regarding their policy on "Adult Image/Video Content" read:
"Any ads that contain non family safe material are disapproved. I noted to the team that the people in the video are not entirely unclothed, but the overall feeling of the video is one of a more adult nature, including promoting mature sexual themes and what appears to be nude content. As such, the video is non family safe. In order to have this video ad approved, you will need to bring it into compliance with our policy."
