The Page Up and Page Down special actions cycle you through the visible pages of any given device you happen to be under at the time. Hidden pages of a given device are skipped over. Under the Home device specifically, the first visible page under that device is your Home page, the page which the remote will display upon initial download of your XCF or after having reset the remote. If all pages are hidden under the Home device then the first page under said device is your Home page. That being said, the Home hard button assignment under your System device and other devices will then determine what is your Home page if of course you are using the Home hard button for this purpose. By default the Home special action is assigned to the Home hard button under your System device which again takes you to the first visible page under your Home device or first page under said device if all pages are hidden.
