Will two processes each holding a given spin lock be seen as ordered by a third process not holding that lock?

In tools/memory-model, there are two litmus tests named
*and *Z6.0+pooncelock+pooncelock+pombonce. *As far as I understand it,
these two files test exactly the same thing: will two processes each
holding a given spin lock be seen as ordered by a third process not holding
that lock? However, ISA2+pooncelock+pooncelock+pombonce says YES, and
says MAYBE NOT. I also read a patch about ISA2+pooncelock+pooncelock+pombonce
If I get it right, is Z6.0+pooncelock+pooncelock+pombonce out of date?
