Not sure how I can elaborate on the title - thanks for input.
Yes, upper back soreness from any deadlift is perfectly normal.
Keep in mind, the weight is hinged on your shoulders. That's where it is attached to your torso. When you bend forward, you have to pull your shoulders back/up in order to not have them pulled down. Your upper back muscles are involved in bracing your shoulders, so it's only natural that you feel the effects of that engagement.
