事件冒泡与事件捕获的先后问题？

我看资料上说现代浏览器对于事件冒泡与事件捕获都是支持的。我写了如下代码：

        <div id="div1">
            <div id="div2">
                <input id="btn1" type="button"  value="按钮"/>
            </div>
        </div>

        <script type="text/javascript">
            var div1 = document.getElementById("div1");
            var div2 = document.getElementById("div2");
            var btn = document.getElementById("btn1");
            
            div1.addEventListener("click",function ( event ) {
                console.log("div1,false");
            },false)
            div2.addEventListener("click",function ( event ) {                
                console.log("div2,false");
            },false)
            btn.addEventListener("click",function ( event ) {                
                console.log("btn,false");
            },false)
            div1.addEventListener("click",function ( event ) {                
                console.log("div1,true");
            },true)
            div2.addEventListener("click",function ( event ) {                
                console.log("div2,true");
            },true)
            btn.addEventListener("click",function ( event ) {                
                console.log("btn,true");
            },true)
            
        </script>
