Ok, so maybe it wasn't intentional.
Now go back and watch the crew carefully. From about :50 on there are six men visible near the pilothouse, five outside and one inside driving. At :57 the five are still outside. But around 1:06, as the boat executes its course change, the men all go inside the cabin.
They know what is coming.
As Lyle Goldstein put it in his excellent piece on Chinese fishing boats:
Finally, there is the strong likelihood that Beijing will continue to use the Chinese strategy of "defeating harshness with kindness" (yi rou ke gang) and thus deploying unarmed fishing vessels or fisheries enforcement vessels to confront foreign vessels operating in its EEZ and claimed waters._______________________
