confused about the limitation of the jsp:include tag

JSP gurus,
I am confused about the limitation of the jsp:include tag. This is what the Marty Hall book says:
"The jsp:include action includes files at the time of the client request and thus does not require you to update the main file when an included file changes. On the other hand, the page has already been translated into a servlet by request time, so the included files cannot contain JSP. Although the included files cannot contain JSP, they can be the result of resources that use JSP to create the output"
Below are my 3 files: main file which includes the 2 JSP files. I am thinking that since the 2 included files - ToolBar.jsp and ContactSection.JSP have JSP tag, this should result in an error. But this works fine! I am confused

Any suggestions/pointers appreciated !!

Main File:
<html>
<body>
<h1>This is the main page</h1>
<jsp:include page="/jsp/test/ToolBar.jsp" flush="true" />
<jsp:include page="/jsp/test/ContactSection.jsp" flush="true" />
</body>
</html>
ToolBar.JSP:
<%
for (int i = 0; i< cookies.length; i++)
{
Cookie CurrentCookie = cookies[i];
String CookieName = CurrentCookie.getName();
String CookieValue = CurrentCookie.getValue();
out.println("Name1 : " + CookieName + ", Value1 : " + CookieValue + "<BR>");
}
%>
ContactSection.JSP:
<%@ page import="java.util.Date" %>
<%-- The following become fields in each servlet that
results from a JSP page that includes this file. --%>
<%!
private int accessCount = 0;
private Date accessDate = new Date();
private String accessHost = "<I>No previous access</I>";
%>
<P>
<HR>
This page © 2000
<A HREF="http//www.my-company.com/">my-company.com</A>.
This page has been accessed <%= ++accessCount %>
times since server reboot. It was last accessed from
<%= accessHost %> at <%= accessDate %>.
<% accessHost = request.getRemoteHost(); %>
<% accessDate = new Date(); %>

Why no one has responded to my question?
