I do believe that during the US leg of this tour that copy bit the dust.. as he said it happened in the States... so we are seeing the last video appearance of it..
I don't know wheter he always used it for Action This Day or if that gig the RS happened to get out of tune in the previous song so he switched. In the case it's the first option, then perhaps Brian used the Flying V for Action in Japan. So sad that part isn't included in the video
