为什么 我照着写 container容器 和 box1容器 是按顺序执行？？？

//HTML代码

<div class="container">
		<div class="box1">
			<img src="images/img1.jpg" alt="">
			<img class="portrait" src="images/pic.jpg" alt="">
			<div class="inner">
				<h1>慕课网</h1>
				<p>慕课网，只学有用的</p>
				<span>查看课程</span>
			</div>
		</div>
		
		<div class="box2">
			<span>&times;</span>
			<h1>慕课网</h1>
			<p>慕课网，只学有用的</p>
			<img src="images/img01.jpg" alt="">
			<img src="images/img02.jpg" alt="">
			<img src="images/img03.jpg" alt="">
			<img src="images/img04.jpg" alt="">
		</div>
		
	</div>

//JS代码

var container = $(".container");
	var box1 = $(".box1");
	var portrait = $(".portrait");
	var open = $(".inner").find("span");
	
	var box2 = $(".box2");
	var close = box2.find("span");
	var imgs = box2.find('img');
	
	$.Velocity.RegisterUI('wangbin.slideUpIn',{
		defaultDuration:500,
		calls:[
			[{opacity:[1,0],translateY:[0,100]}]
		]
	});
		
	var seqInit = [
		{
			elements:container,
			properties:'wangbin.slideUpIn',
			options:{
				delay:300
				
			}
		},
		{
			elements:box1,
			properties:'wangbin.slideUpIn',
			options:{
				sequenceQueue:false
			}
		},
		{
			elements:portrait,
			properties:'wangbin.slideUpIn',
			options:{
				sequenceQueue:false,
				delay:60
				
			}
		}
	];
	
	

	$.Velocity.RunSequence(seqInit);
