From googling, Snow Don departed HK on 2013-06-22 and the US State Department cancelled his US passport on 2013-06-23.

Got the dates mixed up. Apparently they cancelled his passport on the 22nd, after which he departed. As to whether the cancellation catalyzed the flight to Moscow with help from HK is another question.
