No, it is not a new Vector facility, kind of, it is similar, but not true 
Vector.

I think I am stating things correctly.

Give me a few minutes to find your answers, because it is documented, it was 
some of the things I learned from the IBMTechU conference I went to a couple of 
months ago.

From a presentation:
The IBM z13 continues to support the z Integrated Information Processor (zIIP) 
which can take advantage of the optional simultaneous multithreading (SMT) 
technology capability. SMT allows up to two active instruction streams per 
core, each dynamically sharing the core's execution resources.

This must be a misunderstanding...

Perhaps he's thinking of the new Vector Facility for z Architecture (aka SIMD). 
Of course, those instructions work on all PU types.
