Yes, I don't think that clip suggests it happened on any other of his films?
But as the clip suggests, the way Cardinale in particular plays the part in the featured scenes, suggests her reactions are in complete sync and sympathy with the music.
It would be hard (if not impossible) to get that level of symbiosis by doing it any other way. And it makes it all the more powerful.
(Yeah OK, I am a little bit in love with Cardinale, so perhaps I'm a little biased

)
