Mainly because what you are doing is unsupported by IBM. So results are 
interesting. It is also a really good way to wipe out a PDSE entirely if 
you update it from both systems. Done that. I think the reason is that 
parts of the PDSE are buffered by z/OS and not immediately "hardened" to 
the DASD. This is why you cannot share a UNIX filesystem either in this 
situation.
