In (hyper-)P you can change either aperture or shutter speed and the cam automatically adjusts the other to get correct exposure according to the selected metering and program line.
AFAIK the program-line is disabled when overriding Hyper-program settings and going into Hyper-Av or Hyper-Tv. Settings will then be the same as in Av or Tv.
The only way to use program-line and be able to adjust exposure is when using P-mode with P-shift or Sv-mode. (At least it has been working like this on cameras before K-5).
