You make a ranged Strike with a thrown weapon you already have in your hand, Stride, and then Interact to draw another weapon. If you are raging, you can add the additional damage with melee weapons you receive from raging to your damage with the thrown weapon.

Thrown weapons become especially deadly in your fury. You apply the additional damage from Rage to your thrown weapon attacks. If you have the Brutal Critical feat or the devastator class feature, apply their benefits to thrown weapon attacks.

Barbarian Feat

At a glance these seem to add up even though you're effectively doubling up on the bonus which makes me think it shouldn't work.

You never ever add the same thing to a given roll twice IIRC so no, this is just an alternate way to benefit from Rage damage to thrown weapons.
