I think the idea is to form a habit or a tick that is so strong it carries over to your dream. So like, if you commit to wearing a watch everyday, and check it every 5 minutes, eventually you'll do it in your dreams too. Then, you don't have to intentionally check whether you're in a dream, hoprfully you'll just catch the time being wildly different and be like "holy crap this was a dream??"
