Yes.  Yes.
The "Nippon Clip-On" is what you must be referring to.
Since the Airframe life is generally N takeoff-landing
cycles and M hours of flying, ANA (and possibly others)
flies without the wingtips on short flights - and when
they get used up a large number of cycles, they put
the wingtips on and fly them on longer routes to get
the most use out of the airplane.
