That's my understanding also. As Nancy noted, there's an automatic frost protection system for the heater "IF YOU WISH TO OPERATE THE WATER HEATER" in colder temps. It starts the heater once temps drop below 38. If the heater is drained, it would be heating dry pipes - not a good idea.
I use the pink stuff after I blow out the lines. The pink stuff will boil and lose its effectiveness if heated. So I turn it off when I store our rig and turn it back on once I flush all the lines.
