I guess the only reason is because the book may be a bit out of date. This book really focuses on how to use references. They probably created this case to serve as an example. In this chapter it is about using references with File Handles. I think that they were using this case as an example of how to create file handles on the fly with references.
I am not sure why this IO::File is used in this case. They introduce it only as a subclass of IO::Handle and give some examples on how to use it.
Thanks for the help guys,

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
