For the person who's going to hang the flag will hold it up in front of him/her. Look at it, right side up (the crescent moon and stars at his/her top left) in his/her view. Then hang it as it is on the parapet wall.
Hung that way, viewing from the outside will be reversed as seen in your photo.
I find nothing wrong with it, look at our flags hanging on the pole, does it have two different side, looking on one side is straight, looking on the other side is not, so there is nothing wrong with it, it only a person perspective look. Yes I know the flag hang on the other side is very awkward, but some people may see it differently.
