You could. For instance, you might accidentally overwrite an external file containing JavaScript code. Or you might accidentally overwrite and included JavaScript. This can happen with relative ease if a new version of the page has JavaScript that an older, live version does not. In those cases, simply confusing which side of the FTP client represents the client and which the server could resulting in accidentally downloading the older, live file onto the newer file waiting to go live.
The best way to prevent these kinds of mistakes and accidents is using some kind of version control software. This software will keep various versions of the same file, allowing you to "rollback" to a previous version should you need to.
The most popular of these systems are CSV, SVN, and Git.
