Unless I'm mistaken the documentation (in this case in the code comments) is not correct. It doesn't put it in the PageContext, it puts it into the context that's a part of the OGNL ValueStack.
So (I'm guessing, I haven't tested any of this) if you set var="blah" you should be able to use it via <s:iterator value="#blah">...</s:iterator> or in a scriptlet from just the pageContext via ((ValueStack)(((HttpServletRequest)pageContext.getRequest()).getAttribute(ServletActionContext.STRUTS_VALUESTACK_KEY))).getContext().get("blah")
If you want to promote something from the ognl context to the pageContext, look at the s:set tag, with scope="page".
