Using double up procs it if it is OFF cooldown. If it is on cooldown you can fire double up, have it bounce off the first person, activate w, and if it managed to go off cooldown since you first fired double up the second person will take the bonus damage.

To try and clarify more here's an example. You fire make it rain which activates the Sheen proc, auto-attack, and consume the oh-hit, putting it on cooldown. You then fire double-up while it is still on cooldown, it bounces, the cooldown finishes, and before the second hit lands, activate W to gain the Sheen proc. When the second hit lands it will consume the Sheen proc as well as apply the Impure Shots grievous wounds debuff to the target hit.
