Affecting multiple MCs with a for loop?

[Danger Madcow]

Let's say I have ten widgets that have ten items that need to be turned off. What am I doing wrong here?

for(i=1;i<=10;i++){
	var tempWidget = ["widget0" + i];
	trace(tempWidget);
	tempWidget.item._visible=false;
}

The trace returns the correct value yet the loop doesn't turn the ten items off. Why?

for (i=1; i<=10; i++) {
	var tempWidget=this["widget0"+i];
	trace(tempWidget);
	tempWidget.item._visible=false;
}

Excellent! Why is the "this" required though? Is it like saying "Hey, now tempWidget is going to be called this equasion I define over here"?
