So you're basing your belief on the behaviour of a chip that is relegated to 
secondary 
processing functions on a system with a primary CPU that is not manufactured by 
Intel?  
Why would you expect behaviour exhibited by an Intel CPU to be replicated on an 
IBM CPU?  
Especially one that is driven by micro-code where you cannot guarantee the 
implementation of an HLL op-code.  It could (and does) change from release to 
release.
