Loading text from external source

1

In the tutorial with that name there is this code:


on (release) {
    loadText = new loadVars();
    loadText.load("TEXT1.txt");
    loadText.onLoad = function(success) {
        if (success) {
            // trace(success);
            newsBox.html = true;
            newsBox.htmlText = this.myNews;
        }
    };
}

What´s the purpose of this part?


function(success) {
        if (success) {

Is there any chance for “success” to be false?
