That infact appears to be on-air character generator. Watch this video so you'll understand what I am going to say
Now, the Intellistar would have waited until the next LDL cue. It won't change in the middle of the LDL displaying data, auctualy, it wont go behind the old LDL. The old LDL is still on the screen. What this appears to be is a operator error at TWC with a Character Generator system.
If this were to be an new LDL, it would have displayed on the next cue, as I said. Also, as you can see, this new LDL graphic came in much after the old one, but the old one was over the graphic displayed.
People may have their own opinions about it, and I can't change that unless if I just motivated them to not believe my theory. It simply makes sense that it was a Character Generator error over at TWC.
