I think that Buscetta emphasizes Michael's estrangment from personal ties within his crime family. Those closest to Vito were long time companions; those closest to Michael were more like employees. I think it also points out the business side of Michael's machinations which lacked Vito's personal touch.
A very nice point, olivant, and it's reinforced when Michael tells Tom,"Y'see, Tom, all our people are businessmen. Their loyalty is based on that."
