Depth into the scene, if an object is on the image plane that the left and right image with be co-incident, if the objects is deeper than this then it'll left image will be to the left and right image to the right, if it's at infinity then the left and right images, for a correctly setup stereo display) should be separated by the interocular distance (the distance between the eyes), if the object is in front of the image plane then the two images will be swapped. In the case of the stats these are just drawn on the image plane, controlled by an override of the projection and view matrix so it is in effect not computed in stereo at all. If the stats did not use their own osg::Camera to override the projection and view matrix then you'd need to carefully position the drawables in depth and orientation to match the position of the image plane in scene.
