Okay, I think I understand it now:

If you're out in the wilderness, be aware. If you come upon a wolf/bear/cougar, stop, don't run, make yourself look bigger, clap your hands, yell, bang rocks together to scare them away.

But if you're out in the same wilderness and don't see them (although they're there), it's okay to run with music blaring in your ears.

And since wolves never attack people, you don't have to worry about the bears, either.

Gotcha.
