I hadn't seen that before and immediately went back to the other videos. Can't see the flashes in them but in the ones that have a a couple seconds before it starts collapsing, assuming they were charges, it's a pretty clear ripple going up the tower to me like a third of the way in of the building on each side.
Bonus footage 2 , you can see the charges flashing and blowing out the windows along the support beams.
