Duplicate/Should Have Searched flags

Just for reference, I’m assuming the “Something Else” under flagging does not automatically hide posts and that moderators have to manually jump in if a post is flagged for something else. Is this a correct assumption? As the forum I used hasn’t switched to Discourse yet, all I have to go on is this topic on flags, and codinghorror mentions:

Since “something else” can be an infinite number of reasons, I thought filing a flag under “something else” did not apply to this since three different flags could be for completely different things. If 3 “something else” flags automatically hides posts, then there is no need for two new flags – users can still help keep the community clean with something else without having to wait for moderators to manually clean up posts.
