If you have a right XI nn. lesion, answer says you have right shoulder droop and can't turn head to the left.

Is this correct? I'd think think that the left SCN mm. is unopposed so you'd have inability to turn towards the right.

Right SCM turns your head left. You can actually prove this one to yourself, put your hand on the right side of your neck and feel your right SCM flex when you turn your head to the left.
