Yes, one fuel line might feed the main line when on a hill but the other one might feed air. Air bubbles in the line would compress and act just like vapor lock and you won't have fuel pressure at the carb (or throttle body if you have fuel injection.)
You have to pull from only one tank to assure it working properly.
