Sanctum - damage to life but not to resolve

EDIT: This may be intended behavior. If so, I still do not see a return to checkpoint/town message on death.

On the final (fifth) Sanctum boss I took life damage but not resolve damage during the red maze phase.

It's possible I did not lose any resolve during the entire encounter.

Enemies in the Sanctum typically (can) damage both life and resolve, just most of them deal more resolve damage than life damage.

The final boss's final form doesn't deal resolve damage anymore, but deals a lot of regular life damage. So this appears to be intended.

There is a bug, though, where it doesn't show the fail screen if you die without running out of resolve.
