In theory, yes. In practice, it doesn't work. I pasted that shortcode into a TubePress widget, so you can see the results.
One note to save head scratching: We cache into static HTML for non-logged in or non-commenting visitors. I cleared the cache just now, but if I ever forget one must wait at least 1 hour for the cache to auto-purge. If debugging this proves a challenge, I'll just send you an admin invite; if that proves necessary, please PM me whatever email address I should send it to or if I should just create the account and PM you the credentials.
Thanks for the follow up.
