Nauthiz rune and the reverse(?) Nauthiz of Thule Gesellshaft

[loki88]

Hello. I have stumbled upon an image used by the Thule society and Karl Maria Wiligut that many might be aware of (not sure how to attach images here or I would): it depicts the tune with a reverse stroke angling from down to up left to right and not as in the elder futhark Nauthiz angling the opposite. Why? The logo uses a double reverse Nauthiz in its center. Does this reverse the meaning of Nauthiz or something?
