SBMM S.U.B Ray4 HH 5-way toggle switch?

While watching a review for a SBMM S.U.B. Ray4 HH I’ve stumbled upon this comment:

“This is a great bass but it is never in double humbucker mode. It gives you the rear humbucker in full and the front pickups inside coil. The actual HH music man gives you both in full.“

So now I’m wondering if that’s really true? Because if it is I’ll just buy a single H version instead and save myself some money, since the whole reason I’m interested in HH is double humbucker mode.
