I don't know, but I doubt it.
Since there are no actual 'lines' present in the spider morph I really am unsure if it's from a single snake.
However, I doubt it because the trait is dominant, and doesn't slow down their camouflage. The trait seems that it would blend a lot better than albino in the wild would.
And the dominant trait makes me believe that there are more than that one line out there, if they're being used or not, I don't know.
Just my 2c.
