Prigozhin decides "if I'm dead anyway, I'm taking Putin with me"
Lukashenko somehow convinces Prigozhin that "it's ok, Putin changed his mind and won't kill you anymore" - so Prigozhin no longer feels the need to go for a suicide mission (although how Lukashenko convinced Prigozhin of this, I have no idea)
If this had really been about Shoigu or a coup or anything other than just a suicide mission, then the current result makes 0 sense. (But in that case, maybe the situation isn't really over at all)
