I think his point is that sensor-shift stabilization in a DSLR does NOT provide the advantages of a stabilized viewfinder that it does in an SLT or mirrorless.You don't see the image of what you are recording on any DSLR through the OVF- the mirror has to flip up to take the picture in regular mode or live view.because you don't see the stabilized image of what you are photographing/recording.
AF is also not stabilized in SLTs... Which is why I'm surprised so many third-party manufacturers are dropping OS from their A-mount lenses.
I guess the reason for them keeping it in K-mount but not A-mount is because unstabilized AF (A-mount SLT) is less noticeable than unstabilized AF PLUS an unstabilized viewfinder (Pentax K-mount bodies with SR).
I feel like the situations where unstabilized AF would be an issue are pretty limited.
