That is the link of me going to the exact location. I did completely log off my xbox live account from the change profile option within destiny. When I signed back in I unlocked the achievement "Second wind" but the fragment was still not at the location.

In that video you actually went to a different location. It's very very close though. It even looks the same. Behind where you were when you died, there is another triangle shaped section of debris. Check the video I linked again. Edit; in fact, at the end of your clip, during the death screen, the camera pans around and looks directly at the correct location.
