I'm not sure, therefore, that a discussion about exact wording in the attribute is actually helpful. Whatever the person would say would in any case imply that it is related to the video."

Good. Do you also agree that the short text is a "place holder" for the video?

Since the image is a place holder for the video, this is not possible.

Because it can't be both at the same time: represent the video and not
represent it. It sits in the video's place, has video controls over
the top of it, and is for all intents and purposes the video.
Therefore, it cannot also be different from the video.
