Exactly, the last two year survival of control group may be artificially enhanced because the ones that were going to die were already dead in the first three.

Why would they compare the death rate in just the fourth year between the two groups instead of doing a normal survival analysis?

That's what the article seemed to imply. That mortality was higher after year 3 in the intervention group compared to the control group.
