Could somebody explain the "Exempt List" in English?

I don't quite understand why Pouncey has to go through this process. Why does he have to get permission to play again if he already served his 2 game suspension? Does he get to practice after Wednesday when he is off the "Exemption List?"

"The Exempt List is a special player status available to clubs only in unusual circumstances," NFL.com points out, citing the league's manual. "The List includes those players who have been declared by the Commissioner to be temporarily exempt from counting within the Active List limit. Only the Commissioner has the authority to place a player on the Exempt List; clubs have no such authority, and no exemption, regardless of circumstances, is automatic.

"The Commissioner also has the authority to determine in advance whether a player's time on the Exempt List will be finite or will continue until the Commissioner deems the exemption should be lifted and the player returned to the Active List."

The exempt list is more about the team/roster limitations. Pouncey is exempt from the 53 temporarily, so the Steelers don't have to cut anyone immediately. I think they get until Thursday for that.

Thank you.
They released Patrick Morris to make room for him so that is why I am confused a bit.
