For the Group Lift to qualify as a mirror image feature, what must occur?

For a Group Lift to qualify as a mirror image feature, it is essential that skaters pass each other from opposite directions. This creates the visual effect of a mirror image, where the movements of the skaters reflect each other across an axis. The passing motion enhances the symmetry and creates a striking visual dynamic that is characteristic of mirror images in synchro skating.

In this context, options that involve parallel lines or all lifts being executed simultaneously do not emphasize the essential element of contrasting movement directions. Additionally, while unique positions for each skater may be visually interesting, they do not specifically address the requirement for creating a mirror image effect. The emphasis on opposite directions is what ultimately distinguishes the mirror image characteristic in these group lifts.
