The weight capacity per tire for duals is always derated some relative to singles; and so the weight rating in the dual column is not twice that in the single column. While it may come out the same (or close enough to the same) in this case, that's not always true. For example, if the rear axle had 19,000 pounds on it: the correct pressure using the duals column would be right at the top, around 110 psi, but using the singles column you'd figure only 95 psi.
