Also weapon-based attacks not considered to come from Gurthalak will -not- proc it. This is from a sample size of 633 slams from the main hand and the only source of rage was battle shout and berserker rage, absolutely no autoattacks at all. I had gurthalak in my offhand and a garbage green in the mainhand. There were -zero- procs. HOWEVER, if you are attacking with a non-weapon-based melee attack, such as Bloodthirst, then it -CAN- proc, regardless of what hand the weapon is in as long as it is equipped.
