I was initially confused as well. Would be interested in an authoritative answer from the author, but this is what I came up with upon reflection: the behavioral and performance standards he's talking about are the ones that are primarily social and relatively objective. So, for instance, if one of your team members is prone to shouting at colleagues, it's the manager's job to explain that he expects everyone to act civilly. If the team has decided to adopt code style rules or test coverage requirements, and someone frequently flouts those rules, it's the manager's job to tell them they have to follow the team rules or find another team. Stuff like that.
