It doesn't really matter, does it? In either case the only possibility to outbreed the herm trait, is to find a male of the same strain, that is gonna naturally herm in optimal environment without any stress. This means that the male plant has a female gene that is dominant and it's gonna replace the dominant male gene in the female offspring. The stable female needs to be found in the offspring of course, which would mean looking for a needle in a haystack. But it is possible.
What wankdank is doing is, he's taking a completely unstable hermimg female, reversing it (like it's not gonna throw balls in his face in any case) and using that pollen to fix the herm trait.
