If you are talking about the side mounted adjust microtuning truss rod thing on the Pro necks, then yes you are correct. Be sure to only adjust that with loose strings. The trick that someone mentioned, sorry I don't remember who, is put the allen wrench in pointing towards the head of the neck. Then if you loosen it, the wrench will go the direction the neck will be adjusted in, or a looser truss rod, more relief. Tighten, towards the body, right handed, straighten or backwards bow. Hopefully that is not horribly confusing.
