Continuity mistake: Just as John starts running from the Doc's place, he approaches a pole on the street, and two people with an umbrella start to cross the road. The shot changes to in front of John, and the two people who were crossing the road have instantly disappeared. (00:14:10)
Answer: Winston had broken the rules by allowing John to escape in the first place before trying to kill him. This effectively nullified the Continental's immunity while Winston was in charge do to himself breaking the rules. Therefor, John would not be breaking any further rules by killing him on the Continental grounds as it had been desanctified, and thus John would have been cleaning it to allow it become such once more and clearing his own name.
