Because you don't have to worry that crossing your stroke multiple times in a single stroke (again sorry my english) can change the value. A way to do this is to paint a big stroke than erase the unnecessary or have a very low opacity brush so you can match the right value more easily (that is what I did in my thread pictures).
In that case use the Preserve Transparency option for your layer. ( it's a little option in the lower right of the layer thumbnail ). Then you will not change the Alpha value of the layer only the color when brushing.
I don't get it. Okay, the alpha value remain the same but the grayscale value change an that is my problem.
