You two are right. It's about been net zero additional anthropic warming, because, as you said there is some emission we can't cut.
Zero additional anthropic warming result in progressive global decarbonizing thanks to carbon sink. (If the carbon sinks still exist when we reach 0 net emission and the permafrost hasn't thawed yet)
