A couple things. That blog post shows the case of rebasing a single commit and so yes, it doesn't talk about interactive rebase that lets you reorder and edit commits, and it doesn't talk about rebasing multiple commits. In the case of multiple commits, it has to perform a merge operation for each of those commits, that's why you end up seeing the same merge conflicts over and over. For interactive rebase, there are so many scenarios there that it would probably take a few posts to explore them all.
