Twin Throw states
making a full-attack action with a thrown weapon, your first attack fires two thrown weapons.
and Empowered Shot says
You may expend your psionic focus as part of a ranged attack (but not ranged touch attack) to ignore any penalties for range increment for that single attack.
Does this mean even if you full attack, only make a single attack in that that full attack action and use you psionic focus, both thrown weapons' range is still at its maximum range at no penalties?
Is this true:
