Not sure about this. Mrs WH (she works for American) just got home from T3 LHR, and her briefing was that anything other than what was (legally) allowed in the plastic bag was forbidden onto the aircraft. If you bought it in Duty Free, it most definitely did not go onto the flight with you. She says there were numerous instances of SLFs at the departure gate with DF puchased items - they were all sent back to DF to get a refund - no exceptions. (note - this may only be the case for SLFs going to the USA)
