It's common practice for any show that has a rollover for later time zones or for digital posting. A good friend of mine is the editor for weekend Good Morning America, which has an odd workflow where it's only live to a handful of markets (Bangor, DC and I think one or two in Florida) and then re-rolls an hour later for most of the Eastern/Central timezones with a bunch of tweaks to fix errors and insert updates if there's breaking news.
Yeah. It's tempting to hit CBS/Bari/Tony for the edit, since there was all the hype about "transparency", but everyone cleans up a show for a later feed.
