Yep, the turrets on the brass-erector tube Burris's were moved forward for leverage reasons.
Ran into that parallax problem now and then. In 1995 they sent me a new variable once for a big game hunt I was planning, as I recall a 3-9x or so, and the only magnification where there wasn't any parallax was the top end. I tend to prefer magnification somewhere in the middle of that for most big game hunting, so told 'em what was happening. They said that's just the way things are--apparently due to the brass erector tube. It wasn't too long afterward that they started revamping the line-up--without the brass tubes.
Good hunting, John
