I don't think it's on youtube but here's a picture of how it was during the national anthem. I think the ISU probably was more in a twist about how it looks for photos. I think they do want each medalist on each step with no flags even if they are from the same country. Then when it's over you can join the gold medalist for another photo on the top step with the heads of the ISU and technical controllers. I just think they want to keep control of medal ceremony protocol.
