It wouldn't make sense if this arc would be under Infinite Tsukuyomi Arc. All of your points are completely valid and credible, too, and perfectly describes reason for this change.

An arc is an arc regardless, this is obviously a major shift or position in the story; the goals of both protagonist and antagonist are utterly divergent from the other set of goals posed in the beginning of the arc, goals that defined it. I don't see why this isn't sensible.
