Finished book 2. Near the end of chapter 25 they are running to escape the impending explosion. Carl chats with Mordecai and they have this exchange:

Carl: Are there any guards still in the warehouse?

Mordecai: I don't know. Probably a few. They're still moving out to their regular positions. I'm not going over there to look. Now get your asses into that stairwell!

Carl: Okay. Oh, and Mordecai?

Mordecai: What?

Carl: Congratulations.

He didn't answer. Donut looked up at me, eyes wide. "That's right," she said. "He's free now, isn't he. We make it to the fourth floor, and he gets to go home once the dungeon is over." "That's right," I said.

I thought the deal with the manager perk was Mordecai stays their manager for the length of their time in the crawl. Did I miss something? Was Carl simply congratulating Mordecai because they were going down two days early so he would get two days off? Or, is this something I need to keep reading for?
