The jam ends on June 2nd for no one - seems they made a mistake in the video since the term of the jam is 10 full days from the moment it starts. For people that live between eastern Europe and the western Pacific, it will end on June 4th due to time zone differences. For everyone living between the central Pacific and central European time zones, it will end on June 3rd.
You can look at this time zone map to check yourself.
