That means that, like the above reply says, the unit's health is 0.4/Max HP or below, but not quite 0. So the game displays it as 0.

I don't know anything about the lack of healing bug though, it's an obscure situation I never encountered before. Maybe it's a bug as healers need the *displayed* HP to be above zero?
