I'm thinking the bucks were cautious as hell being the decoy didn't look right, thats why they circled down wind Jeff. Not because they thought it was another deer, because they weren't sure what the hell it was. Decoys are hard to use, deer allot of times are not fooled by them. I won't use them, there too blah like, they don't move. From my experiences most of the time the only reasons a buck will come in down wind of something is to wind a scrape, bedding area, feeding area, or try and wind something that just isn't right to them. In the Realtree case, its the decoy.
