[the event calendar] PHP returns variable, but shouldn't

I simply don’t understand why this code behaves the way it does. I just want it to echo eighter A or B, but it writes the the organizer_link and A (like this http://www.google.comA)

<?php
$organizer_link = tribe_get_organizer_link( get_the_ID(), false, true);
if ($organizer_link !== '') {
echo 'A'
  ;}
    else echo 'B';
  ;
?>

tribe_get_organizer_link is from The Event Calendar plugin where I found this documentation: http://tri.be/support/documentation/the-events-calendar-template-tags-organizer-functions/

Can anyone tell me what’s wrong?
