I did the following alterations:

\newcommand{\rrefx}[3]{%
   \protected at edef\curchapter{\thechapter}% removed \hbox{}
   \protected at edef\cursection{\thesection}% ditto
   \protected at edef\cursubsection{\thesubsection}% ditto
   \protected at edef\cursubsubsection{\thesubsubsection}% ditto
   \protected at edef\curref{#2}% here: never raw \edef in LaTeX!
   \def\refsame{#3}%
   \def\refother{#1~#2}%
   \typeout {DEBUG: curref: \meaning\curref}
   \typeout {DEBUG: cursec: \meaning\cursubsection}
   \ifx\curchapter\curref\refsame%
     \else\ifx\cursection\curref\refsame%
       \else\ifx\cursubsection\curref\refsame%
         \else\ifx\cursubsubsection\curref\refsame%
           \else\refother%
         \fi%
       \fi%
     \fi%
   \fi%
}

\newcommand{\rref}[2]{\rrefx{#1}{\getrefnumber{#2}}{\pageref{#2}}}
\newcommand{\vrref}[2]{\rrefx{#1}{\getrefnumber{#2}}{\vpageref{#2}}}
