Interesting Result with Seeing AI and a Mirrored Image

I'm fooling around with print maps again, and this time I printed out a map after flipping it in the Photos app, then inserting it into a Pages document to make a mirrored image. This is so I can get a sighted person to trace the lines of the map with a ballpoint pin on a drawing board to make it tactile. It has names and numbers on it, but I only care about the lines at this time.
Voice over recognizes the image, both in Photos and Pages, as a map and tries to read a bunch of gibberish, I assume because it is backwards.
I checked the printout with Seeing AI, mostly to be sure it actually printed something, and in the Read mode, it reads a bunch of gibberish. However in the describe mode it seems to figure out what the backward letters and numbers are, like the title of the map. I ended up asking it if the letters are backward, and it said they were, speculating that the map was printed as a mirror image, or some sort of verbiage like that.
