It also happens with -Q. It's from init_process (process.c, l. 7152ff):

#if defined (DARWIN) || defined (MAC_OSX)
  /* PTYs are broken on Darwin < 6, but are sometimes useful for interactive
     processes.  As such, we only change the default value.  */
 if (initialized)
  {
    char *release = get_operating_system_release();
    if (!release || !release[0] || (release[0] < MIN_PTY_KERNEL_VERSION
                                    && release[1] == '.')) {
      Vprocess_connection_type = Qnil;
    }
  }
#endif

This is executed before init_editfns has had a chance to initialize
Voperating_system_release (MAC_OSX is defined on my platform).
