I came to a different conclusion after watching footage of a family hunting together at night.

There is also a third very similar white dot on the tip of the tail which is very much more dynamic that the two fixed points on the ears. By moving the tail relative to the ears I would swear the ones in front could at least communicate their own intents to the ones behind them if not issue perfectly silent directives

Interesting theory, Tigers not know to hunt in packs, but you might be right thats it's a way to counter their own camouflage. Do you remember the footage.

It was a mother and juveniles, and it would have been decades ago. Maybe not exactly "Mutual of Omaha's Wild Kindom" but something similar.
