this boils down to:

\unexpanded\def\textormathglue#1#2#3%
  {\begingroup
   \scratchdimen=#1\hspaceamount\empty{#3}%
   \scratchskip=\zeropoint
      \!!plus.5\scratchdimen
      \!!minus.3\scratchdimen\relax
   \ifmmode
     \mskip#1#2%
   \else
     \kern\scratchdimen
     \hskip\scratchskip
   \fi
   \endgroup}

\def\thinglue {\textormathglue+\thinmuskip 1}
\def\medglue  {\textormathglue+\medmuskip  2}
\def\thickglue{\textormathglue+\thickmuskip3}

why the kern followed by the skip? why not just 

\unexpanded\def\textormathglue#1#2#3%
  {\ifmmode
     \mskip#1#2\relax
   \else  
     \begingroup
     \scratchdimen#1\hspaceamount\empty{#3}%
     \scratchskip
       \scratchdimen  
       \!!plus .5\scratchdimen
       \!!minus.3\scratchdimen
     \hskip\scratchskip
     \endgroup
   \fi}
