The original Wolverine was still alive in Deadpool 3. Wolverine 3 is set in 2029 and Deadpool 3 is set in 2024, just 5 years earlier. It makes no sense to me Deadpool's universe was already dying because Wolverine was technically still alive
The Logan Universe is alternate universe and is not a part of the Deadpool Universe. They branch off from the same Universe but its two completely different timelines.
Yeah, I’d think it’s due to the perspective of the TVA being outside and the fact the entire timeline falls apart when the anchor being dies so it doesn’t really matter where on that line you are.
