I can think of some possible motivations:
(1) Some kind of load-balancing thing and/or edge DoH servers. It gives you an opportunity to connect to a DoH server near you. Latency matters for DNS, and for traditional DNS, DHCP takes care of hooking you up with a nearby server. This could give comparable functionality for DoH. (This could probably also be done at the IP routing layer. But it's nice to have options.)
(2) Decoupling. You can change DoH server IP addresses without releasing a new browser build. And anyway, if you did try to do it by releasing new browser builds, you'd have users who don't bother to update.
