Sounds like you use an identical anchor to me. I always thought i had a high anchor that was unorthodox, but i remember seeing pictures of either Pope or Young that had an identical high anchor point. I seem to recall Bill Negley having a somewhat higher anchor as well.
Not everyone has identical physical dimensions, and slight adjustments for alignment/bone on bone contact would be logical. As long as release is clean, and form is repeatable with no stress injuries incurred (and you can hit what you look at) who is to say "not ok"?
