I would prefer to think he's suggesting that diversity is a representation of cultural background, rather than suggesting that between racially different individuals that have had similar life experiences (upbringing, education etc.) there should be segregation. Agree that the cynical view of the role of measures ensuring diversity in the workplace needs expanding upon though. Perhaps he means that nowadays diversity isn't ensuring equality but rather the quotas can be met in a workplace where the minorities are still discriminated against e.g. in any team there are members who do more work than get credit for and vice versa - perhaps he means there's currently a racial bias at play behind this? I don't know, maybe I'm giving too much benefit of the doubt... or too little.
