Picture this scenario... you have 10 or more sites displaying the same content, such as a third party ad or iFrame, and that content needs changing. If you are not at the computer that has the latest backup of those sites, then editing locally and then uploading could be a catastrophe. Also locating the local folders, editing the file and then FTP uploading to each site is a huge chore, even if your FTP settings are optimised with local and online start folders, and mistakes can be easily made like uploading to the wrong site. Whereas it only takes a few seconds to log in using Sharepoint Designer, load the file, edit and save takes a few more seconds, while already thinking about which one to do next.
