Males have XY chromosomes, females XX. When breeders force a female to go hermaphrodite, it produces pollen and pollinates itself, but still only has XX chromosomes, so all the seeds are females. The plants produced from these seeds are normal females, and can be bred to any male. The resulting seeds will be a normal mix of males and females. However...
The original mother (which is actually the mom AND the dad) will have demonstrated a willingness to herm. This trait will often skip a generation (the feminized seeds), but show up with a higher than average frequency in your crossed generation. This is nothing to be alarmed about, but keep a close eye on the plants produced from seeds from your cross.
There are few things worse than having one of your prize females go herm and pollinate your whole grow a few weeks into flowering. You not only lose the crop, but have to tear down the whole room and sanitize everything... lights, fans, walls, floors, ceilings, ducts... everything, or risk lingering pollen violating your beautiful virgins the next time around.
