Holding the horn does not interfere with the turn. That's exactly why you hold the horn when going around the barrel. Since you want to use a tight rein when you're running barrels so it doesn't slip over the horn and you don't have to reach down a long ways to pull it towards you, if you use both hands you are pulling the bit a little bit on his off side which can cause him to go wider around the barrel. Spinning in reining might be different, because if you use your outside hand you can create a "frame" for your horse to spin into. Not sure, don't do reining. Correct me if I am wrong.
