Actually there are no objects in D-BUS only object paths, which are
little more than an implicit argument to method calls, a string with a
path syntax ('/' separators). Method handlers are registered for a
path or subpath. 

The connection is held open but that's just your connection to the
bus. Depending on the implementation of the bindings (between DBUS and
you language), two method calls to a remote "object" could end up
being routed to two different apps : it depends on wether the bindings
use the 'base service' (the unique identifier for a connection to the
bus) or an acquired service name whose owner can change over time
(depending on the options used when the service name was acquired).
