What you're creating is an S1 (selfed generation 1), there's no such thing as an R1.
Hermaphrodism is just like any other trait - S1s are no more likely to be hermaphroditic, provided neither of the parents are prone to hermaphrodism. If you needed STS or another reversing agent to get it to produce pollen, the progeny almost certainly won't have problems.
An S1, or selfed first generation, comes from a female that pollinates herself, be it by natural or forced show of stamen that pollinates the pistols of the plant.
An R1, or reversed first generation, uses pollen from one female plant to pollinate a separate female plant, perhaps a sibling..but not a clone of itself which would be an S1.
When the genes of two plants meet, the chromosomes all get thrown into a proverbial bag, shaken well, and thrown out in different combination.
The resulting progeny show characteristics of both plants in various ways.
Often times when recombining two plants that are polar opposites of one another, ie...a short season indica and a long flowering sativa, the resulting progeny will often show a good high degree of hybrid vigor and health.
On the other hand, if we breed two sibling plants, or plants of the same strain, the resulting progeny are far less diverse. A continuation of generation of a cross of similar genetics can eventually run into a phenomenon of inbreeding depression. The genetic material available (or lack of) for each subsequent breeding can lead the plant to less vigor and sometimes mutations that were once latent, can now show themselves.
When we force a female to pollinate herself, she has a stand of DNA that contains her genes, which is bred to an identical strand of genes. If we think about it, we have cut the available genetic material in half when we self a female. And the result can often times lead to the inbreeding depression I mentioned.
Yes, the two genetic maps of a forced female and herself are identical, but they get shaken up in the proverbial bag I mentioned, and the result can be close to the original but not always. It will depend on how the shake out takes.
Thing is, we have shorted ourself genetic material when we create an S1 and luck must be with us if we are to hope to get seeds that will be identical to the mother and donor.
And we will still need to do a grow and selection of the progeny to find the ones that shook out similar to the moms. We simply can't trust that S1 seeds will result in the same plant. Chances are there that it can, but also that it won't.
A pollination for R1 seeds is almost identical to using a full on male for pollination. The recombination will take place exactly the same, only there will be no male chromosome to work with.
