no plane expert perhaps zaphoid(sp?) will be in here to explain it better but i think the plane can move with the lift fan open because it has the rear engine that seems to be able to rotate to either slow decent or take off depending on if its landing or taking off
to have that make a bit more sense i think the fan provides uplift while the rear engine provides thrust if that makes sense

Drag is a function of the square of velocity. At the very low speeds the lift-fan is employed in, it probably doesn't matter too much. It certainly "looks" wrong on takeoff, though.
