Why is Cosmic dawn and Cosmic Dusk Rakan and Xayah respecively an inconsistant image

While searching for a skin concept for a new Aatrox skin that would be worth spending money on I saw something that really bugged me. the splash for Cosmic Dawn Rakan and Cosmic Dusk Xayah at least from a regular art stand point and spatial standpoint 2 different pictures. I thought that the background and the characters were separate initially but after a few minutes i figured out that the picture was flipped. just using spatial logic these two photos cant exist with the same background as for both of them to have a front facing pose in each of the 2 pictures they would either have to be roatated (which i think should have happened) or flipped which for the characters means that they would have to be on the opposite side of the star (the sun imitating star) in the background but would also mean that the further twinkling stars in the background couldnt be in the exact same spot behind Xayah and Rakan. If they could take the same picture with the same background they would either have to swap hands to do the same pose using their backs or like i said they should have done in the first place rotated the photo so in one case Xayah is on the right and Rakan the left and one case Rakan the left and Xayah the right. Im not sure i make 100% sense but it really messes with my spatial awareness. https://2.bp.blogspot.com/-i7YM2vhbk_8/WPAaZtc8AUI/AAAAAAAAiU4/489-xzkZuro7fCx39TPyELw-cc_SijeBQCLcB/s1600/a35bb6d3af7c808a.jpg https://1.bp.blogspot.com/-GoIad4Sdf6U/WPAaYss9nKI/AAAAAAAAiU0/RYiR27lD5MA8YO7syFY4pzq5PJs0bX93wCLcB/s1600/903d61657dce6729.jpg
