You need additional trigger for that operation.
Its all about adding event to another trigger.

• TRIGGER 1
  • Events
    • Map Initialization
  • Conditions
    • <stuff here>
  • Actions
    • Set importantUNIT = (triggering unit)
    • <stuff here>
    • Trigger - Add to TRIGGER 2 the event (Unit - A unit comes within 256.00 of (importantUNIT))

• TRIGGER 2
  • Events
  • Conditions
    • <stuff here>
  • Actions
    • <stuff here>

As you can see, second trigger has no event event at first, but after trigger 1 runs, it will have new event - which normaly can not be added. So now it looks like this:

• TRIGGER 2
  • Events
    • Unit - A unit comes within 256.00 of (importantUNIT)
  • Conditions
    • <stuff here>
  • Actions
    • <stuff here>

That event just work if the "Unit" is placed on your map not created by triggers after
Then, i think this will work as same as the result of that event:

• Trigger 1
• Events
  • Time - Every 0.40 seconds of game time
• Conditions
  • (Number of units in (Units within X range of (Variable Y set to the position of the unit you want to check if there's any unit nearby)))) greater than 0
• Actions
  • Action blah blah..

That's it, Remember to clear the Variable Y (leak)
Well, i think this would work too spinnaker. And Explain:
Condition: use Integer Comparison for that
Variable Y you could set it in a trigger that use Map Initialization

Edit: Seems to be i'm not alone
Edit 2: sorry, edit the trigger again
Edit 3: a little explain

Man, your trigger is also proper, however mine too.
Nothing stands between changing event:

• TRIGGER 1
  • Events
    • Unit - starts the effect of ability
  • Conditions
    • <stuff here>
  • Actions
    • Set importantUNIT = (Triggering unit)
    • <stuff here>
    • Trigger - Add to TRIGGER 2 the event (Unit - A unit comes within 256.00 of (importantUNIT))

Your dicision when to add this.
