From the outside, this is indistinguishable from randomness. But from the inside, the difference is that the individual had a say in what the action would be.
Where this tends to get tangled up with notions of a soul, I think, is that one could argue that such a free choice needs some kind of internal state. If not, then the grounds by which the person makes the choice is a combination of something that is fixed and their environment, which then intuitively seems to reduce the free-will process to a combination of determined and random. So the natural thing to do is then to assign the required "being-ness" (or internal state if you will) to a soul.
But there may exist subtle philosophical arguments that sidestep this dilemma. I am not a philosopher: this is just my impression of what commonsense notions of free will mean.
