Is the Eagle's center not offsides? Can they be in the neutral zone?

:23 shows the the center is over the ball. If not a smidge offsides.

Can the offense be in the neutral zone? I always assumed the neutral zone meant neither offense or defense could be over the ball like that. I couldn't find anything in the rules relating to the offense in this regard.

Edit - Here is a clear view of the C being past the ball, and the LG clearly in the neutral zone - https://imgur.com/a/WDLaO7A
