I showed you, in the very next sentence:

 If so, that's different from not receiving the Shift modifier
 at all.  E.g., for me, after `emacs -Q', `C-h k' tells me this
 for `S-TAB':

   <backtab (translated from <S-tab>) is undefined
            ^^^^^^^^^^^^^^^^^^^^^^^^^

That is what I see, with emacs -Q.  If you are not seeing the part in parens
then I'd guess that Emacs is not seeing the Shift press at all.  Someone more
knowledgable can perhaps help you further with this.
