I just got to watch it 4 times over the course of a round trip to Singapore to San Francisco. It is so bizarre that it does keep my attention, so in that sense it is helpful. As was mentioned above though, during the english translation portion, the dancers are just doing fill-in moves, so there is no connection between their actions and the instructions. I fully expect that if there is ever an issue, someone will attempt to do a praise dance as a response, based on what they saw in the video.
