I believe that the initial torque is used to "seat" the components before applying the final torque. Then you loosen the bolt so that you can apply the final torque with a smooth and constant rotation until the torque value is reached without any influence from parts that may not be completely "seated" upon initial tightening.

I might be wrong too, but that's how I would interpret that specification.

As for torque-to-yield bolts, I have ALWAYS seen their tightening specified as a torque value plus some number of degrees additional rotation beyond the initial torque.
