I hadn't realized this part of Payamps signing. It makes a lot more sense now, and I am much more comfortable with it. From MLBTR:
The Braves are investing $2.25MM in the idea that Payamps can regain his old form with a change of scenery. Payamps is out of minor league options and thus can’t be sent to Triple-A without first being designated for assignment, though his guaranteed contract provides leverage for the team. Because Payamps has less than five full years of MLB service time, he would have to forfeit any remaining guaranteed salary if he refused another outright assignment in favor of free agency. The added salary might also act as a bit of a deterrent for other teams who might otherwise be interested in claiming Payamps off waivers following a DFA.
If he can't break camp as one of our 8 best relievers, we can stash him in AAA. If he refuses, we don't have to pay him.
Also, at some point in the season, it will be more beneficial for him to request his release than to sit in AAA collecting a check. The later in the year you sit in AAA, the less opportunity to have to catch on somewhere else and try to land another contract for 2027. So either he's decent/good, and we get a bargain, or he's not so good, we DFA him, and he is either claimed, elects FA, or sits in AAA until we might need him or until he decides he wants an opportunity somewhere else.
