This is wrong.
A bridge does not need an ip address itself to pass traffic from interface A to interface C, so it could look like this:
hw interface a <---> bridge b <---> vm interface c 192.168.1.3 none 192.168.1.4
Keep in mind that bridging takes place on layer 2: https://en.wikipedia.org/wiki/Bridging_%28networking%29

But when you attach them to bridges and don't have IP addresses on the bridges, then they are unreachable.
