Maybe her daughter is a runner or a little too adventurous. I had one who would just take off running down the road periodically. He was probably close to 8 before I just sent him outside to play unsupervised. My other kids tend to follow the rules and stay around the house. They were much younger. If you are comfortable leaving your child outside unsupervised, then you should do what you are comfortable with. I wouldn't assume that different parenting styles means that there is a right and a wrong. Kids are different. Parents are different.
If she truly feels that she is right, you are wrong, and you are using her to supervise your child, then she can use her words and talk to you about it. Otherwise, I would assume that it's fine.
+1 to this. My first was a runner and I needed to stay within eyesight until first grade or so. My second is completely different. OP I would let this go unless neighbor is otherwise micromanaging interactions.
