Even whilst taxiing, the brakes can heat up. On the takeoff roll, some residual brake drag exists and given a "short" turnaround, hot ambient conditions, long taxi in and out you can take off with with hot brakes, which can take time to register on the sensors. On my small aicraft the maximum brake temperatures are recorded up to ten minutes after the event. Once retracted, the airflow around the uppermost wheels is negligible. So given a delay in indications and hot brakes this makes sense.
