Kled E(Joust) VS Yorick's Passive

[Gameplay] Kled's E kills Yorick's Ghouls by hitting them. This is unusual since Kled's E deals damage to all targets in its path, making it an aoe ability, or not single target. Yorick's Ghouls die when hit by single target abilities, auto attacks, and tower shots. AOE attacks are supposed to decrease the Ghouls HP bar instead of killing them. Kled's E however simply kills them instantly as though it were a basic attack.

1. Have Yorick summon Ghouls, either via q/passive or ult.
2. Have Ghouls attack Kled.
3. Kled uses e through the Ghouls.
4. All the Ghouls die.

This has happened multiple times throughout many games on both sides and I have seen it in current patch. As a side note Kled E also kills Zyra plants as though it were a single target ability.
