What is an "outie" in the context of this paragraph?

Mark's innie awakens in Devon's home and finds himself hugging Cobel. While excusing himself to find Devon, he calls Cobel by name, alerting her that the overtime contingency has been activated. Cobel calls Milchick and has him check the security office. Mark privately reveals to Devon that he is in innie form; Devon tells him of Gemma's death, and learns that "Mrs. Selvig" is Mark's boss. Mark encourages Devon to report Lumon's misdeeds to the press as Lumon likely controls the police. Irving wakes up in his apartment, discovering his outie's paintings and background in the U.S. Navy, and finds a map and employee directory in the closet which he uses to locate Burt. Helly wakes up at a Lumon gala where she learns that her outie is Helena Eagan – daughter of Lumon CEO Jame Eagan – who underwent severance to build public support for legalizing the procedure. Cobel races to the gala and attempts to stop Helly from making a scheduled speech. Milchick reaches the security office and cuts his way through the makeshift restraints Dylan has placed on the door. Helly gets onstage and tells the crowd of the innies' subjugation and torment. Irving arrives at Burt's house only to find he is already in a relationship. Mark finds a photo confirming Ms. Casey to be Gemma. He rushes to tell Devon, but is only able to say "She's alive!" before Milchick tackles Dylan, deactivating the overtime contingency and reverting the three to their outie state.

Based on the provided paragraph, it's not clear what is an "outie". However, based on this sentence, "He rushes to tell Devon, but is only able to say "She's alive!" before Milchick tackles Dylan, deactivating the overtime contingency and reverting the three to their outie state.", it seems like an outie is a state that a person can be in and that the state can be switched on by deactivating the overtime contingency.
