rear washer hose routing at front of vehicle

So found this from a manual. Now even more confused. The hose that is squirting water when I push the stalk has been routed to the, US, driver's side and according to this the rear wiper washer hose goes to the passenger side. More work to do tracing this one. On all the older cars I have owned I seem to spend most of my time chasing down weird things PO's did.

On an 06 to 09 RR the rear wiper wash tube runs from the pump in the drivers side front corner of the truck, across the front bumper, under the cover, up over the right front wheelwell inside the fender structure, down the passenger side A pillar, along the rocker (I think you can see it up above the ESC reservoir tank) I think it comes inside the truck at that point, runs along the under the rear door, up over the right rear wheel well then dips down under the rear fuse panel, and up the D pillar under the roof fabric and out thru a grommet into the upper rear tailgate near the center of the gate, and finally meets up with the rear wiper assembly. The only tubes that come across from the drivers side are the ones for the front windsheild sprayers.

The front sunroof drains are located down on the firewall, behind the plastic wheelwell liner on both sides. and drip out just inside the jacking pad at the front edge of the doors.
