That is true. However, if done improperly the water heater will be damaged. Much like furnace maintenance, not everyone should do this.

The primary problem is not shutting off the heat to the water heater when draining. If the gas or electricity is disconnected, the water heater will not be damaged when drained. Although, there is no guarantee the drain valve will not start leaking.
