That is normal for the SSR, if you wanted it to go on or off when the signal isn't present you would add a pullup or pulldown resistor on the signal from SSR, I know you don't need that just saying. The controller does set the pin LOW and HIGH but it's reversed in the code, LOW is on, HIGH is off. If all your outlets are wired the same you can swap the LOW/HIGH in the code that you found, only one location for each. However if you're only adding a couple like this to already wired power bar we can add an if statement so it does right way for proper outlet number. Let me know your setup and we will get it right.
