As a passenger on said EK001 today, and someone who has been a passenger on quite a few go-arounds in my time, I would like to raise a few comments without the risk of being shot down like xtypeman....
Firstly, you are all correct - the crew took it back up, headed back towards east London, and the couple sat in the centre section near me were pretty much blissfully unaware what had happened, until they saw clouds out of the windows where once west London was... it was that routine.
But I would be prepared to swear that we actually touched down before the go-around. Are ones that late usual? It was a hell of a bumpy approach, the ailerons and spoilers were twitching well - and the second landing was heavy enough to break a lot of glass in the bar. Nasty day today, clearly!
