The Hida arranges his bones…?

I saw a video in which Rabbi Mordechai Eliyahu tells the story of an Italian Jew who participated in the removal of the bones of the Hidda in Italy for burial in Israel. How in Israel, on the mission of the Hareltz Nissim, Rabbi Eliyahu went with a certain person and an unknown person and received a small box from the pilot…
There was also a fresh body that had been flown in and the family took the body and left the coffin. Rabbi Eliyahu and his assistants put the small box in the large, respectable coffin, opened it, and it was a mess of bones, etc.
Turn to the Chida, arrange your bones, and with a loud noise, the Chida arranges itself…
Skull on the head, etc.
In the large coffin where we were buried at the end.

I later saw on Wikipedia that they cite it in the Hida article and even cite part of the video as a source.

Does the rabbi buy this?
Rabbi Eliyahu is not held to be a bluff…
