I don't "know", so pure speculation on my part, but maybe they were trying
to create another visual clue to help prevent this exact type of accident.

OK... But what I don't understand is why would they have two runways that
are the same surface width, but it is listed as a 75 ft runway they way it
is marked? It seems to me that if they are the same surface width, they
would mark both of them the same usable width.
