That's the way that all Wacom touch screens work - there's a fine mesh of wires beneath the display which detects interruptions in an electric field caused by the stylus. This cannot go "above" the display or it would interfere with it; it's always beneath, because, unlike a resistive touch screen, it does not rely on physical contact with the stylus.
As you can see from my profile, I have a number of different book readers. Comparing, side by side, the Neo with the Kindle, the CyBook, etc, the screen is absolutely identical in appearance. There is no touch layer "above" the eInk display, as there is with the resistive touch screen of the PRS600 and 900.
