Why would there be a single numeric threshold?

You can pack many, many satellites into the same orbit without any danger, for example – as long as they move in the same direction. Let's make it 1000 for this thought experiment.

On the other hand, just two moving in opposite directions are obviously going to crash.

So is the number of "safe satellites in all of LEO" 1000 or 1?
