Facebook API and backdated_time for Videos

With a Page Access Token i can change the photos publish date with backdated_time parameter.

What about videos?
I receive and error when i try to use it as well saying it's abandoned from 2.3. I can query again the API updating with backdated_time but only within the date the page was really created.
With photos i can use a date before the real publish date of the page.

Are you spam? I'm trying to figure out why you can set photos to a date before the site was published and a video not.
