When you add the host ethernet interface to the bridge, you do not route
packets and you do not have a "guest subnet". It's all one, just like
connecting the guest to the same switch the host is connected to.

Connecting to the bridge connects the interfaces on layer 2, routing
is not part of this and not required. Also, for connectivity to the
outside, a routed guest network also needs proper routes on the host
network. You can do that, but it adds lots of complexity.
