Duplicate FB Scripts?

I see your plugin adds script like this to the footer area:

<script type="text/javascript" src="http://connect.facebook.net/en_US/all.js"></script><div id='fb-root'></div><script type='text/javascript'>
	         FB.init({
	            appId: '',
	            status: true,
	            cookie: true,
	            xfbml: true,
	            oauth: true
	         });
	      </script>

My theme or other plugin already added this FB script needed for FB like buttons:

<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&appId=237796379721707&version=v2.0";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

I am wondering if these two scripts are the same and if there are any potential conflicts?
