i understand about you lack of understsanding what i am talking about due to your aikido backround, but i thought you have bjj and submission wrestling too... wow what did they teach you in ground work???
If I may interject (and hopefully avoid an online scuffle), Ironman is refering to exactly the same thing you are refering to. However, the terminology you are using is different. It can be seen easily by when he says "It keeps your opponent off of his center and tipping over" and your saying "not having the bodies in a line." In either case, both of you are addressing the principles of dynamics and unbalancing (kuzushi) within grappling. Just from different viewpoints.
Where Ironman's description points out that by creating a distance from the opponent and keeping his body line off center would help from getting slammed (probably via dakiage/high hip-lift, aka "powerbomb") because their center of balance is off. Now this can be done by actually shoulder-crawling away from your opponent (which Ironman didn't explicitly post), or by (in your post) "shifting his body yo his right" to upset the opponent's balance and tighten the triangle.
In either case, you should not be directly underneath the opponent because you'll be in a position where their posture/center of gravity will allow them to slam you (as applied under the principle of dynamics). By moving away or off to the side, you take away your opponent's center of gravity making them off-line and unbalanced (via kuzushi) helping prevent the slam.
Lastly, I will agree that the size difference definitely matters in this case. With someone closer to your own size/weight, the adjustments will go a lot farther to upset their balance/center of gravity. With a larger opponent, they have more leverage and outright strength to compensate for that.
