You are right the press release does not explicitly
say that the light meter will work with the K and M
lenses. Neither does it explicitly say it does not
work. 

My guess is simply: When you use a FA, F  or A lens
set to the A position, you will deactivate the shutter
release when the lens is not set at A. This avoids
malfunctions or wrongly exposed pictures when the
camera is set to program mode but the lens is not to
A. This has been critisised in many tests of the
MZ/ZX-6/7. 
When you use a K or M lens you will activate shutter
release when the lens is not set at A. Just that
simple.  

I don't know if this is true (or overoptimistic) but
is seems common sense to me. Besides they also state
the soft lenses in their press release. They have no A
position. 

Enjoy,
