They made a big deal of Sisko's promotion from Commander to Captain, though,
without changing his functional position as the commanding officer of Deep Space 9.
Sometimes the writers use these ideas of rank for dramatic effect. Tom Paris gets a multi-episode arc about being demoted and then repromoted. Sometimes, dude, it's just for the drama. The episode you reference was one of the early Dominion arc episodes, so, yeah, it was a way to say, Sisko's gonna get more latitude to do what needs to be done against the Dominion, he has slightly more authority given the challenges ahead.
It's not always about the rank as much as it is about what it symbolizes.
EDIT, Also, AIUI, Avery Brooks was not happy that he was the only lead that wasn't a Captain, and during talks between the seasons he not only was adamant that he be a Captain, but he also insisted that he be allowed to shave his head and grow his goatee, as he was accustomed to.
