From my understanding of it, after 3 characters, 1. Dragons are unlimited 2. story dragons and dragon wall dragons give souls 100% unless it's a re-visted dragonwall 3. Random encounters only have a chance to yield a soul.
think of it from the Role play view, Dragons are back, they're probably pumping out babies, and since you didn't take that particular dragon soul, Alduin will use it for a new dragon.
