Typical deployments use your core network for routing. The exception to this is sometimes guest VLANs that are not routable and live only on the controller and are NAT'd out. There are also some use cases for the controller acting as the gateway in some remote networking deployments. In your case, there is not an obvious explanation for this.
For other thoughts, review the Default Gateways and Routes section of the Aruba Mobility Controllers VRD.
