Why the Chair, Why is this necessary?

My question is why is there a friggin chair behind Miquella during this cutscene, like what purpose does this serve. I doubt Radahn is chilling behind Miquella, using him as a footstool. If I was begging someone to honour a deal I wouldn’t have my back turned to them. So what’s up with the chair?

What are you guys thoughts? Questions? And concerns? Because idk, it seems pretty redundant to me…unless Radahn is the chair…dark souls style.
