On Unix-based systems, the shell command ln x y creates y as a hard link to file x. There is only a single file, so if you edit y, you will also change x.
If wanted, you can configure Vim so that it will break hard links whenever a file is written, providing a backup is made. In that case, editing y would automatically remove the link, and create a separate file, leaving x unchanged. The Vim command (in vimrc) is:
set backupcopy=auto,breakhardlink
