Here is the docstring:

  (org-babel-tangle-file FILE &optional TARGET-FILE LANG)

  Extract the bodies of source code blocks in FILE.
  Source code blocks are extracted with `org-babel-tangle'.
  Optional argument TARGET-FILE can be used to specify a default
  export file for all source blocks.  Optional argument LANG can be
  used to limit the exported source code blocks by language.

I suppose it is optional so you don't have to specify a default export
file for all source blocks.  What if you want to tangle two or more
files from the same Org buffer?

Well, by default :tangle no, so unless you've changed this somewhere I
think Babel will defer to the default value.
