Setting the backend has an effect on the next figure window that is
created.  It doesn't change the backend in use for currently open
figure windows.  So try this instead:

  backend ("fltk")
  figure (1)
  plot (rand (10))

  backend ("gnuplot")
  figure (2)
  plot (rand (10))

You should get one FLTK+OpenGL window and one gnuplot window.
