I didn't spot that. I just thought that it was the chaos of getting all the DCs to sit nicely and look the same way.
I once watched a mother duck trying to get her large brood up a weir. Several times she'd just about chivvyed all of them up and one or two would splash back down and I could see her roll her eyes, tell all the ones on top of the weir to not move and jump down to get the rest of them up only for some of the others to go over the edge of the weir.
She had about 10 ducklings but by the time she'd got them all up and on their way, she must have counted about 25 climbing up the weir.
