JMO-777 has posted what appears to be a schedule of test flights rather than a round-the-world promotional sales tour, which typically has the aircraft spending a day at each stop where it can be viewed by the airlines concerned and then they're taken up on a joyride before the aircraft moves on to the next destination.
Most of the destinations listed above wouldn't feature on a sales tour, and several important ones which you'd assume would be included are missing.
An aircraft visting Irkutsk, Petropavlovsk, Keflavik, Easter Island, Iqaluit, Cold Bay, Wake Island and Perth among others is undergoing testing - not a sales tour, which would feature London, Amsterdam, Hong Kong, Atlanta, Dallas etc.
Given the success of the World Sales tours of the B757-300 and B767-400 3 years ago, since which time Boeing has secured just 1 new customer (Northwest for the 753) I would think Boeing will save themselves the expense. Airlines will choose to buy an aircraft or not, irrespective of whether it has been paraded at their HQ
