It requires creating 3 different objects,
Right, that's because the OVS support in NM is modeled after the ovsdb
schema, with separate entities for bridges, ports and interfaces. When
you create a bridge with 'ovs-vsctl add-br br1', that actually
generates 3 objects:
# ovs-vsctl show
Bridge br1
Port br1
Interface br1
type: internal
If there was only a single NM connection profile for the whole bridge,
it wouldn't be possible e.g. to attach another interface to port
"br1", or to describe more complex setups in a declarative way.

The order shouldn't matter; if it does, that seems a bug.
If it helps, "man nm-openvswitch" provides an overview of OVS support
in NM.

This configuration is certainly supported. If you found any problems,
please report a bug.
