Mordekaiser Q Empowered Auto Attack isn't reset by the activation of Titanic Hydra

This is either intentional and poorly worded (Q - Mace of Spades - Mordekaisers next three hits are empowered. ...) or functioning as intended and needs clarification that the attacks are spells instead of "empowering" regular attacks. Anyways, when you activate Titanic Hydra while Q is active it doesn't reset for two quick hits.

1. Press Q and attack
2. Activate Titanic Hydra before next attack would normally hit, should reset auto attack
3. doesnt

Found this while playing in practice mode with cooldowns on and off.

I know nobody plays Morde anyways but hey this might help him.
