Stupid Trussrod question

I have a DR Heartfield whose trussrod has to be adjusted from the other end of the neck, i.e., the end which protrudes into the body.

Now, my question here, which is admittedly stupid as hell, is: When tightening the trussrod from this end, do I do so as if turning the rod in the exact same direction as if it were being tightened from the headstock or do I just tighten it right-tighty like turning a normal screw?

The reason I'm wondering is due to my cluelessness over how the trussrod is set in the neck when the adjustment is performed from the body-end of the neck. My guess is that the truss rod is essentially upside down instead of rightside-up with the adjustment on the bottom.

Does this make ANY sense at all?!?

 

Thanks, Milothicus - I thought that was probably the case, but I wanted to be sure.
