I believe Aizen was referring to the Espada, and their Fracción, as a group, when recieving Ulquiorra and Yammy, rather than their status as Menos. If Aizen had 20 Vasto Lorde under his command, then why was Aaroniero (a Gillian) made an Espada? Besides I doubt that a Vasto Lorde would settle for becoming a mere Fracción.
