You may find that the monitors in a monitoring policy cover most of the monitoring needs you have. However, there may be cases where you want to apply a specific monitor to a group or device separately from a monitoring policy.
For example, the monitoring policies for SQL monitor default instances because the instance name is required to collect performance counters and monitor the Windows services. Generally, default instances are used, but you have a single customer with an important database on a named instance. Creating the monitors directly on the device allows the monitoring to occur as needed without creating a monitoring policy for use with a single device.
