No, that is not what it means. You are reading WAY too much into that. It does say the it is expected to be "More Even" Does not in any way say they are going to split it evenly between all 71 schools.
Like many have said those with more members or those with MORE REPRESENTATION in the playoff will get more. In no way will they agree that if the PAC adds a bunch of G5s to get to 16, but only gets 1 team in the playoff, that they will get more just because they have 16 teams. Do you really think the SEC getting 4 teams in the playoff is going to say its Fair for the PAC10 with SMU, SDSU, Boise, Air Force, Memphis, Tulane, and 1 team in the playoff....gets the same per team/conference? Because its fair? Yeah dont think so.
Every conference would be running around adding all the G5s just to get numbers. In your scenario the B12 could add teams to get to 20, give the G5s half share and make out like a bandit. That is not how it is going to work.
You are taking something that says one thing and making it another.
