I think based on Hunter/Prey Doomsday acquires adaptations that allow him to counter and defeat threats that once killed him.
It's like if kills you with a bullet to the head and you rez with bullet timing speed. It doesn't necessarily mean you're immune to the bullet, just able to counter that threat.
Certainly though Doomsday did also show the ability to become immune to certain attacks without even dying.
