The last two are given to provide two different perspectives in sitting seiza with both geared toward a "budo" way while the first is provided as a "karate" way. This is the first time I have actually seen one that promotes a "karate way of sitting seiza."

When I searched out sitting seiza on the Internet most tended to be either of these two versions but with varying differences as to specifics which I would take as normal. In my current view of Japan and kata-ized things that a specific kata would govern the process of sitting seiza.

Anyway, my curiosity is up a bit and I look forward to many interesting conversations/threads on this subject.
