Well, it's not formally described yet, while these are all sauropods that have been published in 2014. Not to mention that the news of the new titanosaur came out maybe two days after I drew this. Leinkupal was close to not being included, actually.
The paper actually addresses this. "‘Nanotyrannus’ does not exhibit the extreme longirostrine morphology of alioramins. ...Therefore, if ‘Nanotyrannus’ is a distinct taxon, it does not appear to be a member of Alioramini, and may represent a separate acquisition of longirostrine morphology among tyrannosaurids."
