It doesn't work for me, "Vyr" is invisible in both cases.

This is my example file:

------------------------------------------------------------------
\pdfcompresslevel=0
\nopagenumbers
\TeXXeTstate=1

\def\verticalrule{\smash{\hbox to 0pt{\hss\vrule 
      width.4pt height0pt depth\vsize\hss}}}

\def\showcenter{\leavevmode
  \verticalrule
  \kern.5\hsize
  \verticalrule
  \kern.5\hsize
  \verticalrule
}

\def\strut{\par\hrule width1sp height\baselineskip\par}


\parindent=0pt
\showcenter


\centerline{\beginR Vyr hVyryM\endR}
\strut
\beginR\centerline{Vyr hVyryM}\endR
\strut
\centerline{\beginR 123 457 789\endR}
\strut
\centerline{\beginR\hbox{123 457 789}\endR}
\strut
\beginR\centerline{\hbox{123 456 789}}\endR
\bye
------------------------------------------------------------------

\showcenter only makes sense if \parindent=0pt.  \strut is used to
split the text into different strings.  You get a BT...ET environment 
for each line then, instead of one containing the whole text.  The
only purpose is to make the output file more readable.

What I get is this:

If you compare the pdf output of the lines 

   \centerline{\beginR 123 457 789\endR}

and 

   \centerline{\beginR\hbox{123 457 789}\endR}

you'll see that interword glue is not calculated properly unless the
text is inside an \hbox.
