You are right. I have only one screen, but XineramaIsActive(mDisplay) 
return true and XineramaQueryScreens(mDisplay,&num_screens) set 
num_screens to 1.

Man page says
      Option "Xinerama"  "boolean"
              enable or disable XINERAMA extension. Default is disabled.

But with xorg 7.2, Xinerama is enabled by default and it can't be 
disabled  => see https://bugs.freedesktop.org/show_bug.cgi?id=11505
