Yes, the tongue weight is on the TV. My way of visualizing it:
Imagine the TT frame welded directly to the TV frame. All of the weight forward of the TT axle(s) - the tongue weight - would be on the TV frame. Without a ball, there would little rear end sag of the TV because of the lack of a pivot point and the TT would be level.
Now imagine there is a hitch ball, but no WD bars. The rear of the TV wants to drop down due to the tongue weight, but when you see that, you put a steel bar between the TV tailgate and the propane tanks (No, please do not try it!). Now the TV and TT stay level.
WD bars pivot from side-to-side to allow cornering and allow the TV and TT to go over vertical changes in the road, but perform much the same weight transfer that a solid bar would.
In some forum (maybe not in JOF), there is at least one very detailed force analysis of the weight transfer using a WD hitch.
