Remove channeling dummys

[Shoto]

So, i have a unit that casts an ability based on Death and Decay, and i have triggered the ability aswell, to make a dummy cast a non damaging earthquake for the effect and the slow.
but i want to trigger that when the unit stops channeling, the dummy is removed.
that works.
but when multiple units use the ability at same time and one disrupt it, i get problems. Can someone help me with my triggering?
and please, no jass if posssible.

Trigger 1

• Shattering
  • Events
    • Unit - A unit Begins channeling an ability
  • Conditions
    • (Ability being cast) Equal to Shattering
  • Actions
    • Set temp_point = (Position of (Casting unit))
    • Set temp_point_1 = (Target point of ability being cast)
    • Unit - Create 1 Dummy for (Owner of (Casting unit)) at temp_point facing Default building facing degrees
    • Unit - Add a 11.00 second Generic expiration timer to (Last created unit)
    • Unit - Order (Last created unit) to Orc Far Seer - Earthquake temp_point_1
    • Trigger - Add to shattering interruption <gen> the event (Unit - (Casting unit) Stops casting an ability)
    • Trigger - Turn on shattering interruption <gen>
    • Custom script: call RemoveLocation (udg_temp_point)
    • Custom script: call RemoveLocation (udg_temp_point_1)

(Trigger 2 is initially off)

          • If - Conditions

Use generic unit event, unit stops casting an ability.

• Untitled Trigger 046
  • Events
    • Unit - A unit Stops casting an ability
  • Conditions
    • (Ability being cast) Equal to Starfall
  • Actions
    • Game - Display to Player Group - Player 1 (Red) the text: stop

Use either a unit indexer (Bribe's unit indexer) or a hashtable to bind the dummy to the caster.

Here's a very simple example: http://www.hiveworkshop.com/forums/pastebin.php?id=hnp2rd

I didn't even remove leaks.
