Hi Greg, Yes, the way you read the documentation is correct. Ad Ids may be reused across ad groups. As I mentioned in my previous post, AdGroupAd is not the same thing as Ad. Ad is the actual underlying entity, and AdGroupAd is a link that associates an AdGroup and an Ad. A typical example where you might see AdId getting reused across AdGroups is when using is shared Ads.
