I understand perfectly well that black horses sun burn and go brown in places. I also understand that this can happen in both summer and winter coats. I live in Australia, I am well aware of the sun.
However. A black horse will bleach first in areas that have the most sun shining on them. Just like a person. You don't burn on your belly if you are tanning your back. A horse is the same - the soft areas along their belly is the LAST place you would expect to see the heaviest bleaching. This is why paler colour in the lower flank is such a good indicator of brown - you can assume the flank should be one of the darker spots on a bleached black.
