No. The trailer will want to return to center because of the cams! Think of it as trying to pull a log out of a ditch as opposed to dragging one across the flat ground. Let go of the log in the ditch half way up and it will go back to the bottom. Same theory goes to the dual cam. Now stop dragging the log on the ground at will stay where it stops (friction sway bar/EQ). Very simple physics really!
The cam simply is a rounded surface which slides along the bar slope.
If the cam is moving away from center, the friction force increases.
If the cam is moving toward center, the friction force decreases.

I said dragging, not rolling. and yes a log will slide back down just like the DC will. and yes the friction increases as the WD bar slides up out of the cam, but it is also being forced back down by the same friction.
