I think that any sort of vore, regardless on weather or not it's going in or out, involving the vagina is classed as "unbirth". Because if someone is of mature enough age to willingly climb out of a vagina, it's clear that they had to have gone in there at some point, which would be, in AJ's case here, when RD crashed into her. That would have been the original unbirthing, and now this is what we see as an aftermath.
