How to detect a unit not killed by KABOOM?

[WKWebsite]

I have created a scoreboard, like this: (let say)
Event:
A unit dies

Condition
Owner of Dying unit is not equal to owner of killing unit.

Action
Set kills = kills + 1
Game Text Display: String (Name of Kiling unit) has pawn (Name of dying unit)

The condition i use is to ignore the calculation for the hero with Kaboom ability (suicide), which means when Kaboom hero casted kaboom n killed himself. This is not calculated as a kill.

But this condition seems doesnt work at all, even thought i tried with:
dying unit no equal to killing unit
unit type of dying unit not equal to killing unit.
triggering unit not equal to kiling unit.

I really have out of idea. Please help.
I Will give you credits in my map. (only 1)
Thanks. =)

Thanks~!

Thanks so much~!!!

Finally i can release my latest version of dota.

This "Kiling unit not equal to No Unit" works to detect the goblin is suicide, but if in my 2nd trigger doesn't work well. Let say:

1st trigger:
Unit dies,

killing unit not equal to no unit
(so kaboom suicide not counted)

kills = kills +1
Game text: Name1 has pawned Name2's head.

2nd trigger:
Unit dies
killing unit equal to no unit

Game text: Someone has killed himself.

Once i use Goblin Sapper to kaboom a person,
The 2nd trigger's text also displayed. How to ignore that unless he suicide himself without killing anyone.

Just additional question. I already add ur name in my map credits.
