it saves when you die too, it's ironman.
In practice it's just lots of corpse runs though already-cleared areas, it's not nearly as hard to play ironman in 2.0 as in 1.0. When the zone would also reset after your death you'd need to have a dedicated spare set of gear just to help you get back to your body and retrieve your favorite gun or whatever. That was fun, because you would always be aware of how much risk you're taking and how far you're extending and you might not have enough ammo back at base to make another run to your body if you die here...
