WCAG technique H44 test procedure for radio buttons and checkboxes

Hello,

I have some questions about the WCAG H44 test procedure for radio buttons
and checkboxes: http://www.w3.org/TR/WCAG-TECHS/H44#H44-tests

One of the steps in the procedure says: "Check that there is a label
element that identifies the purpose of the control after the input element"

My questions are about the "after the input element" clause and are as
follows:

   Should the test procedure prescribe where a label resides?
   If yes, does "after the input element" mean visually or physically?  For
   example, may a label physically reside above a button and the author
   uses CSS to render it to the right?

Thank you.
