Yes. If you want that setting to apply to just you, put it in
~/vimfiles/after/syntax/tex.vim. If you want that setting to apply
to all users of that computer, put it in
"C:/Program Files (x86)/Vim/vimfiles/after/syntax/tex.vim".

Right. That's because that file is sourced before
$VIMRUNTIME/syntax/tex.vim so your setting was being made first and
was being overridden by the setting in $VIMRUNTIME/syntax/tex.vim.
($VIMRUNTIME in your case is "C:/Program Files (x86)/Vim/vim73".)
