Just my two pesos worth,
If logging PIC time for job application purposes, most are interested in Part 1 PIC time...i.e. the guy with the four stripes who signed for the plane. Southwest last time I checked allowed the logging of sole manip. if typed in the jet as eligible for PIC time. Again, I haven't looked at their website in years so it may have changed.
So yes, if your the four striper in the bunk, bathroom, or downstairs taking a smoke break

you're logging Part 1 PIC time.
If you're not interested in the logging of PIC for job application purposes, the logging of flight time under Part 61 allows the logging of PIC time under many different scenarios.
