I hate to make a "what he said" comment, but this is really excellent advice for beginners with git.
Just learning the very basic actions will get you up and running to gain experience. I have found that many nuances of git are difficult to learn by reading theoretical examples, but fairly easy to understand once you encounter and research a similar problem in your real workflow.
If you have co-workers whose workflow you can copy then I don't think it is needed, but if you want to start a project from scratch with Git then having a plan like this can be really helpful.
