No, there's no extension in mercurial that makes branches behave like git branches. That is clear in the 160 comments where I even created a challenge for anyone to try to do the same in mercurial, and curiously, people have criticized my videos, scripts, and every little thing possible, but none have actually shown how it's possible to do the same in mercurial. So no, you can't do the same, that's the whole point. If you think you can, you are most likely mistaken, but feel free to show how in the comments of the blog, and expect a prompt rebuttal.
