if statement ignored with onPressUp function

I don't get it. At the 'onPressUp' function I want the 'button2' movieclip to disappear and 'buttonAn' movieclip to play. But only if it is over the 650 y coordinate. I added the if statement but it is ignored.

var root = this;
this.button2.visible = false
this.buttonAn.visible = false

function main()
{
	createjs.Touch.enable(stage);
	root.mouseDownListener = root.button.on("mousedown", onMouseDown);
	root.pressMoveListener = root.button.on("pressmove", onPressMove);
	root.pressUpListener = root.button.on("pressup", onPressUp);
}

function onMouseDown(e)
{
	e.currentTarget.offset = { y: (e.stageY / stage.scaleY) - e.currentTarget.y };
}

function onPressMove(e)
{
	e.currentTarget.y = (e.stageY / stage.scaleY) - e.currentTarget.offset.y;
	{
	if (e.currentTarget.y > 650)
	root.button.visible = false
	root.buttonAn.visible = true
	}
}

function onPressUp(e)
{
	if (e.currentTarget.y > 650)
	root.button.y = 275
	root.fallingShape.play();
	root.button2.visible = true
	root.buttonAn.play();
}

main();
