I've posted this image a while ago, before the forum crash.
That's what's happening when you set the \org set far off to the side (the the left in the example), and rotate the sub by 2 degrees along the z axis. That 2 degree would be a rather big jump on the screen. If the \org point was further out, the jump will be even bigger.
If you rotate the sub along the y axis, the sub will shift horizontally. If you rotate along x axis, it'll just rotate along x axis in spot - it won't make the sub move.
