[Newbies] Returned values

While studying DBus code I came across a method that appears to set a class
variable and return the value. In DBusConnection>> sessionBus

  ^SessionBus := self getBus: 0 from: SessionBus

and SessionBus is a class variable. Why return the value? Why not have the
sender examine the value of SessionBus? Is it only a matter of style or is
this more efficient?
