It could be from her grazing and her back being more exposed to direct sunlight then her neck. I've seen this happen before.
My friend had a gelding who had a bad leg injury and he was in stall rest. They set up a little stall outside so he can get fresh air and eat a bit around that area. After a couple of weeks my friend started to notice he was bleaching only on his left side because he only stood with the sun to his left lol!
