The "old man" Zangetsu is not a quincy, but rather the embodiment of Ichigo' s Quincy powers. In addition, in Yhwach' s battle with Ichibe Hyousube he used a "blut" ability that destroyed everything around it until their was nothing more to destroy. This is symbolic of how certain quincy abilities consume surrounding reishi until there is nothing more to consume. By creating a set barrier around Seireitei they were able to allow for a stable area for the Shadow Territory.
