Axe culling blades instant kill Damage?

I Read somewhere that axe does 100000000 physical damage (killing blow). So if someone uses blademail during the killing blow, Will it kill axe??

Solution 1:

No. If the target is below the HP threshold, all buffs are dispelled and then they take killing damage. In Dota1 it was a ton of physical, but in Dota2 I think it's just a kill.

Solution 2:

According to the Dota 2 Wiki it still does 100,000,000 damage. Prior to dealing the damage all buffs are removed from the unit including blade mail.

Solution 3:

I can't post comments but it will go through Dazzle's Shallow Grave.

The only thing that stops Culling Blade from killing is having enough HP to start with.
