I believe that article would only apply if BA cancelled your flight within 14 days of departure.
I had the same issue with my FAO-LCY (September 9th) which has similarly been cancelled. I had booked to LCY because CE was available for Avios which it was not to LHR. The result is I have now been rebooked in CE to LHR, which is fine too.
