Yes, you have to be careful editing a live page, which is why it's better to copy it out to your sandbox (or profile) and once finished copy the final version back in to live page. I've got no control on who will edit a page and when. Another tip is to select the source (control+A) the copy it to notepad or just the clipboard (Control+C), before you publish the final version, if there are any editing conflicts you will still have the version you have created.
