This is only true if one of the files that you've changed has 100% no changes between the branch you're currently on and the branch you're switching to. Even stuff that would normally be auto-merged will not allow you to switch branches. I still usually give it a try, and then stash when that gives me a problem. With 12 developers and some high-churn files, it's pretty common that 2 people are doing something with the same file, even with branches that only last 1-2 days.
