Haven't watched the video, but Urs recently beat guys who probably wouldn't have been top 10 let alone top 6 at the O, so it's still unlikely he'd be competitive against the top guys. In that sense he would be better off skipping this year and growing and refining for next year.
But bodybuilding still probably has the "paid his dues" bullshit, so he might as well go to the O this year and get that out of the way.
