Теоретически понятно, но не получается пока. Буду думать дальше как это употребить.

Не получается, может что-то не туда пишу?
Trace одновременно выводит true и false.

stage.addEventListener (MouseEvent.MOUSE_MOVE,onMoseMove);
function onMoseMove (e:MouseEvent):void
{
 
var position:Number = qw_mc.x
 if(var1 == false){
if(position <= 0){
    setURLLoader("text1.xml")
	var myTween3:TweenLite = new TweenLite(qw_mc, 2, {x:-275});
}else if(position <= 550 && position >0){   
    setURLLoader("text2.xml")
	var myTween4:TweenLite = new TweenLite(qw_mc, 2, {x:275});
}else if(position <= 1100 && position >550){    
    setURLLoader("text3.xml")
	var myTween5:TweenLite = new TweenLite(qw_mc, 2, {x:825});
 }
 
}
}

var var1:Boolean = false;
trace (var1);
 
function changeVarValueToTrue ():void{
    var1 = true;
	trace(var1);
}
function changeVarValueToFalse ():void{
    var1 = false;
	trace(var1);
}
 
 
play2_btn.visible = false;
 
play_btn.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void
 
{
 
	var myTween:TweenLite = new TweenLite(qw_mc, 1, {y:-100, ease:Quart.easeIn, onStart:changeVarValueToTrue(), 
										  onComplete:changeVarValueToFalse()});
	var myTween:TweenLite = new TweenLite(play_btn, 1, {y:0, ease:Quart.easeIn});
	var myTween:TweenLite = new TweenLite(play2_btn, 1, {y:0, ease:Quart.easeIn});
	play2_btn.visible = true;
removeEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
}
 
play2_btn.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler2);
function fl_MouseClickHandler2(event:MouseEvent):void
{
 
	var myTween:TweenLite = new TweenLite(qw_mc, 1, {y:100, ease:Quart.easeIn, onStart:changeVarValueToTrue(),
										  onComplete:changeVarValueToFalse()});
	var myTween:TweenLite = new TweenLite(play_btn, 1, {y:200, ease:Quart.easeIn});
	var myTween:TweenLite = new TweenLite(play2_btn, 1, {y:200, ease:Quart.easeIn});
	play2_btn.visible = false;
removeEventListener(MouseEvent.CLICK, fl_MouseClickHandler2);
}

На меня неожиданно снизошло просветление и всё заработало. Если кому-то интересно, то сейчас выглядит так:

stage.addEventListener (MouseEvent.MOUSE_MOVE,onMoseMove);
function onMoseMove (e:MouseEvent):void
{
 
var position:Number = qw_mc.x
 if(var1 == false){
if(position <= 0){
    setURLLoader("text1.xml")
	var myTween3:TweenLite = new TweenLite(qw_mc, 2, {x:-275});
}else if(position <= 550 && position >0){   
    setURLLoader("text2.xml")
	var myTween4:TweenLite = new TweenLite(qw_mc, 2, {x:275});
}else if(position <= 1100 && position >550){    
    setURLLoader("text3.xml")
	var myTween5:TweenLite = new TweenLite(qw_mc, 2, {x:825});
 }
 
}
removeEventListener(MouseEvent.CLICK, onMoseMove);
}

var var1:Boolean = false;
trace (var1);
 
function changeVarValueToTrue ():void{
    var1 = true;
	trace(var1);
}
function changeVarValueToFalse ():void{
    var1 = false;
	trace(var1);
}
 
 
play2_btn.visible = false;
 
play_btn.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void
 
{
 
	var myTween:TweenLite = new TweenLite(qw_mc, 1, {y:-100, ease:Quart.easeIn, onUpdate:changeVarValueToTrue()});
	var myTween:TweenLite = new TweenLite(play_btn, 1, {y:0, ease:Quart.easeIn});
	var myTween:TweenLite = new TweenLite(play2_btn, 1, {y:0, ease:Quart.easeIn});
	play2_btn.visible = true;
	event.updateAfterEvent	();
 
}
 
play2_btn.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler2);
function fl_MouseClickHandler2(event:MouseEvent):void
{
 
	var myTween:TweenLite = new TweenLite(qw_mc, 1, {y:100, ease:Quart.easeIn, onComplete:changeVarValueToFalse});
	var myTween:TweenLite = new TweenLite(play_btn, 1, {y:200, ease:Quart.easeIn});
	var myTween:TweenLite = new TweenLite(play2_btn, 1, {y:200, ease:Quart.easeIn});
	play2_btn.visible = false;
	event.updateAfterEvent	();
