Yes, but I got caught out trying to go back airside - I'd taken the route out via the train to put a bag into left luggage. I was still technically airside as I wasn't identified to the system when I used the auto passport gates, so my BP was flagged as an exception. It took a lot of head scratching in the Gold Wing with a supervisor being called down before I could get back. So although it works brilliantly, be careful if you want to go back.
