Setting as "Official Series" for a playlist...why?

[babyteeth4]

On your playlists, you get the option that says: "Set as official series for this playlist". When you click the information button, this description comes up:

"Use this setting for sets of videos uploaded to your channel as part of an official series. A video cannot appear in more than one series playlist. YouTube may use this information to modify how the videos are presented or discovered."

What are the advantages to doing this? Why would I want to restrict a video to being in one playlist? Has anyone experimented with this to see if it helps optimize SEO? I guess I just need a better explanation as to what this does and why I'd want to (or not want to) do it?

If it's not broke don't fix it. Youtube has a way of playing with things that work perfectly fine..

I guess better SEO and presentation, though I think its for more stuff like WebSeries, which don't really need to be in more than 1 playlist.

I don't think that it is applicable for your content but it is a nice feature.
