first up, yes it is a hack, i dont even need to watch the video to confirm it because i have the same thing on my account, however, this isnt a real time mod or done from a JB PS4, this is simple, you load up your ps3 account on a jb PS3, RTM it, then use the same login on your PS4, simple, you have the same shit on your PS4 account that you did on your PS3 profile
