That is true, you can not have a temperature different in the room with the thermostat. But with careful blocking of part of the radiator by covering it with a box or pad, the temperature of other rooms will not reach the temperature of the room with the thermostat. Reducing the ability of the radiator to give off heat will lower the temperature in the other rooms.
This is safer than shutting the radiators off in other rooms which may expose them to freezing in extremely cold weather. They will be hot, but not able to heat the room as well, using less heat for the boiler to make up. This is the purpose of zoning without the expense of changing the system by installing zone valves or adjusting the flow of water in the less-used areas. The savings can cut the heating bill in half to be used for permanent savings from insulation.
