Axiom known to EVERY Linux user (hmmm... may be not every after all? hmmm...) is that man pages for gnu tools are VERY inaccurate. Use info instead.

Oh yes. Far more. Most are pointless or just plain wrong.

Yet again: man pages ARE NOT reliable source of information about gnu tools. So your letter is not wrong this time. Just pointless :-)) As usual...
This is from info file :
-- cut -- By default, `tar' uses an archive file name that was compiled when it was built on the system; usually this name refers to some physical tape drive on the machine. However, the person who installed `tar' on the system may not set the default to a meaningful value as far as most users are concerned. As a result, you will usually want to tell `tar' where to find (or create) the archive. The `--file=ARCHIVE-NAME' (`-f ARCHIVE-NAME') option allows you to either specify or name a file to use as the archive instead of the default archive file location. [skipped] If you use `-' as an ARCHIVE-NAME, `tar' reads the archive from standard input (when listing or extracting files), or writes it to standard output (when creating an archive). If you use `-' as an ARCHIVE-NAME when modifying an archive, `tar' reads the original archive from its standard input and writes the entire new archive to its standard output. -- cut -- and this is from `tar --help` output: -- cut -- ARCHIVE may be FILE, HOST:FILE or USER@HOST:FILE; and FILE may be a file or a device. *This* `tar' defaults to `-f- -b20'. -- cut --
Default name for file is compile-time options and most distributions have it set as "-" (standard input/output)...
