Answer
Dear M. Warwick,

Mounting is a dominance behavior, as well as mating, so it's still possible that the baby is a male.  Please see:

No matter what sex the bunnies are, they will need to be spayed/neutered in order to prevent fighting and unbonding, which can happen when sexual maturity hits.  Prevent fights at all cost!  Even if no serious injuries result (and they surely can!), even a small fight can cause a permanent rift between the bunnies, preventing permanent friendship.

Hope this helps!
