The purpose is mostly just to indicate to the browser the text that follows should be treated like a h2 and to tell it exactly how much of the text is to be considered a h2 there needs to be an ending to it.

What you need to understand that to a browser

<h2>Title of the page</h2>
<p>A paragraph in the page.</p>

is the same as saying 

<h2>Title of the page</h2><p>A paragraph in the page.</p>

which is the same as

<h2>
Title
of
the
page
</h2>
<p>A                paragraph      in          the        page</p>

That it to say the spacing means nothing to it so the best way of specifying how much text needs to go into a particular tag the opening and closing tags need to be specified.

<h2> is a "opening" HTML tag meaning "Heading" it has 6 different sizes. <h1> being the biggest and <h6> being the smallest. With MOST HTML tags you need to add a 2nd "closing" tag to complete the line of code. The closing tag looks like the opening tag except with a / . Like this </h2>. In this case... he opened the <h2> tag on one line, and closed it </h2> on another line. Then he concatenated them (added together) to create the full line.

so actually he did it to get larger sentence size? because it works w/o any HTML tag as well.
