You're missing a feature:

this is the original trick:

if=C2=A0 =C2=A0 =C2=A0multilocs[i] =3D=3D 1 :=C2=A0 % begin
elseif multilocs[i] =3D=3D 2 :=C2=A0 % between
elseif multilocs[i] =3D=3D 3 :=C2=A0 % end
fi ;

and in lmtx we have

if=C2=A0 =C2=A0 =C2=A0 multikind[i] =3D "single" :
elseif=C2=A0 multikind[i] =3D "first"=C2=A0 :
elseif=C2=A0 multikind[i] =3D "middle" :
elseif=C2=A0 multikind[i] =3D "last"=C2=A0 =C2=A0:

Also:

=C2=A0 =C2=A0 =C2=A0 path p;
=C2=A0 =C2=A0 =C2=A0 =C2=A0p :=3D ( llcorner multipars[i]
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 -- lrcorner multipars[i] =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 -- urcorner multipars[i] =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 -- ulcorner multipars[i] =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 -- cycle )
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 enlarged (EmWidth,EmWidth)= ;
=C2=A0 =C2=A0 =C2=A0 =C2=A0fill p withcolor boxfillcolor ;

can be

fill multipars[i] enlarged (EmWidth,EmWidth) ...
