[JASS] Help implementing a spell

Boomerang... lol

Edit: lol this is a WOP (Workaround-oriented programming)

Everything I want is to make a boomerang spell that throw two blades in in +45 and -45 angle and them they go forward the enemy and return to the caster... But when I throw the right blade goes to the right point but the left one start a infinite rush across the map...
I already tried many ways, this is the actual (poor) version of the trigger.
I already tried with move orders but the max movement speed is 500. that make the blade slow and if both target and caster have a good movement speed they can ruin the spell.

        return false

Hm?
What's the problem?

I edited the first post after someone gave me another ideia of what I was wanting to do...
But that made me back to JASS... I'm not home right now so I can't post the trigger anymore. xD
