It seems to me that if you take two spherical people in vvakum, then yes, you will get a traditional heterosexual couple. However, if you deal with real people, then there are a lot of nuances like: why they changed their gender, what attracts them to each other, etc. (Maybe they get away from the idea that their partner was originally of a different gender)
He will be a heterosexual, as it seems to me, since both of them were originally of different sexes, which then changed to again opposite to each other.
