They literally added errata to clarify the situation. I mean you're certainly entitled to house rule it that way but that's not RAI, at least for 2014 rules as they stand.AFAIC, if you are reduced to zero hit points, you are gone, and once you are gone, the second ability never comes online. Unless the ability that brings you up to 1 hit point specifies it takes effect before other effects are applied, it clearly doesn't. by the time Mister Zombie is making his Constitution saving throw, he is already disintegrated.
