Yes! I think this is exactly right. At least, it's exactly right if the OST track is microedited to remove the original betting scene and most of the hadkerchief scene. I think it's still possible that the OST track is a non-edited full recording, of a cut of the scene that had no betting or handkerchief bits at all (perhaps when there was only going to be 2 films). I assume we'll find out eventually!
Wha? Don't be mad, this was a great collaborative effort to figure out Shore's intentions!
