Here, it says this instead:

  A “backup file” is a copy of the old contents of a file you are editing.
  Emacs makes a backup file the first time you save a buffer into its
  visited file.

In the two cases you posted, the buffer was not saved into the file
visited by the buffer, so this is not "backup" in Emacs terms.
