Why does jQuery .after() not chain the new element?

I am curious why jQuery's .after() does not chain, or "provide you with," the new element that you create with it. It seems to me like it should, but I am no expert and was hoping someone could shed some light on why it's a bad idea. Here's an example to see what I would like from .after():

Here is some markup:

<div id="content1">
    <p id="hello1">Hello</p>
</div>
<div id="content2">
    <p id="hello2">Hello</p>
</div>

Here's what I want, but this replaces "Hello" with "World!":

$('#hello1').after('<p />').text('World!');

This does the job, but it sure is ugly:

$('#hello2').after('<p />');
var $newParagraph = $('#content2 p').last();
$newParagraph.text('World');

This is nicer, but I'm not entirely sold: (maybe I should be?)

$('#hello1').after( $('<p />').text('World') );

Note this is obviously a simplified example, that is, "<p>World!</p>" is not what I want to add, my real world problem is more complex than that.

Thanks for any thoughts.
