Your pics do not show it well but by deciphering your post you essentially leave the tie around the mouthpiece and then use another zip on top of that and the tubing if I am understanding it right. In that case your method would be ok in my book. What I am referring to is the practice of using one tie to put mouthpiece and tubing on. That can lead to failure in my experience. My original configuration that failed was pimped off to me by several DIR proselytizers. It failed twice but my QR buckles and other gear that I was severely berated for has never failed.
