This is actually a feature ... emacs only makes a backup file once every
time you visit the file. So if you want to make multiple backups, you
have to either go out and back in before it'll create another backup file,
or you have to delete the buffer and load it again. Next time you save, it
will create another backup file.

The reason for this is that you don't get too many backup files, which
I've found very useful.

If you specifically want to create a backup file each time, there is always
'write-file-hooks' where I suppose you could modify save-buffer in files.el.
