So, if they are 2 distinct people and not even twins, it's not the same thing as Regina & the Evil Queen, which is her split persona. While the same person, there is always a physical transformation between Jekyll and Hyde, so using two different actors would just be to really maximize the showing of the physical transformation. I think it is a clever way to do it.
