By "different group," they basically mean a new little niche clade within titanosauria, which in itself is a derived group of sauropods. Still a sauropod, still a titanosaurid sauropod, but it doesn't fall into one of the existing titanosaurid clades like nemegtosauridae or opisthocoelicaudinae or aeolosaurini or anything like that.
