In Xanathar's Guide to Everything, the Path of the Zealot gives a barbarian the "Rage Beyond Death" ability at level 14 (emphasis mine):
Rage beyond Death
Beginning at 14th level, the divine power that fuels your rage allows you to shrug off fatal blows.
While you’re raging, having 0 hit points doesn’t knock you unconscious. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don’t die until your rage ends, and you die then only if you still have 0 hit points.
RAW, this says that regardless of your death saves, if you receive healing before the end of your rage and have 1 HP, you remain alive regardless of the outcomes of your death saves.
Is that the case? And is that RAI?
