You've removed the answer to that question.  The full text says:

                                                          Then, in each
     iteration of the loop, the END-TEST is evaluated; if true, the loop
     is finished.  Otherwise, the body FORMS are evaluated, then each
     VAR is set to the associated STEP expression [...]

which clearly tells that the test is done _before_ the BODY is run.
Right?
