skyfall - Does Patrice wound Bond in the initial scenes in the right or left shoulder?

Bond takes a bullet in the right shoulder in the opening sequence and it is clearly shown during his fight with Patrice on the train. Subsequently, as he is recovering, the wound is shown in a reflection in the mirror, in his right shoulder as was earlier witnessed. Much later in the film, as Bond is trying to pry fragments of the bullet from his shoulder for forensic analysis, the camera shows him face on trying to probe the wound now in his left shoulder. How could the director miss this?
