Stop the "capital swap" viewpoint. That is a mgmt tactic that they use with their own children. The point of the provision is for US. Many of the great trips (high block in short periods) run into rest issues. This provision allows pilots to have high efficiency trips and more days off with certain provisions (close/good hotel with reliable transportation, or none required).
The company cannot "impose" it, a better way to look at things is the scheduling committee can "incorporate" it ONLY if it helps and WE are OK with it.
