Mordekaiser interaction with Sated Devourer

As Mordekaiser's abilities scale with AD and AP, and his ult works well with dragon, I figured why not try going rageblade + devourer in the jungle. So I tried that in a custom game and got sated, but was rather disappointed at how Sated Devourer interacts with Q - Mace of Spades. You would think that either one of the following two things should happen:

1: The sated passive applies 2 iterations of Mord's Q, e.g. if he activates Q, his first basic attack applies the first damage from Q and his second attack (which applies the sated passive) applies the second and third damage. 2: The sated passive applies one iteration of Mord's Q twice, e.g. if he activates Q, his first basic attack applies the first damage from Q and his second attack (which applies the sated passive) applies the second damage twice.

I found however, that when you activate Mace of Spades, none of the 3 basic attacks that are affected by MoS interact with Sated Devourer at all. Sated Devourer is basically on a pause until MoS is finished.

Personally, I would think the 1st proposed option would be the most satisfying with what you'd expect from the interaction. It might even put Morde in a good spot in the jungle, granted your teammates have enough CC to be able to gank and fight a bit. Either way. I hope that the current situation - no interaction between MoS and Sated at all - is unintentional.
