I don't see a conflict.  Imagine you were able to look through yourself but still see what you see in the mirror.  The words on the bottle would be reversed and so would you.

Ok so  a person turning around changes the image axis as your right and left reverse.  When I first read the OB comment I went to a mirror then I raised my right hand to my right ear and it was still on the right side in the mirror image but holding a bottle of Listerine up produced the words backward. I'm looking straight into the mirror so my axis of perception has not changed. Why do the word on the Listerine  show up backwards?

Mirror image

If one looks in a mirror, one's image reverses (e.g., if one raises one's right hand, his left hand will appear to go up in the mirror). However, a mirror does not "swap" left and right, any more than it swaps top and bottom. A mirror reverses the forward/backward axis, and we define left and right relative to front and back. Flipping front/back and left/right is equivalent to a rotation of 180 degrees about the vertical axis (in the same way that text which is back-to-front andupside-down simply looks like it has been rotated 180 degrees on the page). Therefore, looking at an image of oneself with the front/back axis flipped is the same as looking at an image with the left/right axis flipped and the whole figure rotated 180 degrees about the vertical axis, which is exactly what one sees when standing in front of a mirror.
