Answer 1

You throw the boomerang so its path is curved. If it follows the curve around long enough it will form a circle, so you throw it curved a really long way and it comes back to you.

The returning boomerangs were practice/showcase ones. If you use a boomerang for hunting to stun something, it won’t return after it hits your quarry
