Two AP controllers on different VLANs. How are APs finding the controller on the other VLAN?

We have two AP management VLANs with a Mobility Express controller on each. At times, when the controller on one VLAN is rebooted, the APs on its VLAN join the controller on the other VLAN.

I don't have any ip forward-protocol commands on my core for anything CAPWAP/LWAPP, and I do have DHCP option 43 configured.

how are these APs finding the other controller?
