To clarify, I shone the light under the floating pickup - parallel with and toward the neck. This allowed me to see the width of the piece of wood to which the pickup is attached.

I do not get the impression that the entire neck extension is floating on these guitars, btw, the part holding the pickup might but the rest seems to sit really flush to the top.
