First, consider your own mirror image. You do not easily perceive your front and back as reversed even though that is what happens when you face a mirror. In fact, the mirror seems to reverse your left and right. Left and right are usually defined by where your front and top are and people tend to take their image as the starting point for defining their image's left and right. If you move your right hand, the "mirror hand" that moves is still on your right side. There's no reversal in that sense. However, your right hand is perceived as the left hand of your image. The perceived reversal of intrinsic left and right is "lateral inversion". We often perceive these left-right mirror reversals. So, that's why mirror reversals are called "lateral inversion", even though that's not usually what the mirror does directly.
