My guess is that in the circumstance you described it will not make any difference. However, in my printing I have found that to get a print with the highlights and shadows where I want them, the soft exposure must be determined first. My rationale for this is that the soft exposure also affects the shadows more than the hard exposure also affects the highlights. So if I start with the hard exposure first and get the shadows where I want them, a subsequent soft exposure will overexpose the shadows. Conversely, if I set the highlights first (which also begins to expose the shadows), the subsequent shadow exposure darkens the highlights very little (if at all,) while "finishing" the shadow exposure.
That's my story and I'm sticking with it.
