I participated in a different thread a long time ago on this same topic. The consensus of that thread (which I didn't search and find to link here) was that the long press of the parking brake button engages the parking brake "tighter" than the normal short press parking brake. It was generally agreed that if you are in Drive and do a long press, the electric actuator that engages the brake is energized for a slightly longer period of time, which since it's a jackscrew mechanism, means it's squeezing tighter. I tend to agree with this consensus in my own experience.
I would also suggest that it's possible that using the long press parking brake application every time/excessively, if it is indeed a tighter hold, could cause premature wear of the rotor or jackscrew or electric actuator, etc. and that may be why Tesla has made two different engagement levels of this brake.
As to the idea that regenerative braking "hold" mode is only using the motors to remain stopped, I do not believe that is the case. The "creep" mode section in the manual says something about the car may roll backwards on an incline even with creep mode enabled. This seems to indicate that they don't use the motors to prevent movement. Also you can feel the brake pedal move when hold mode engages.
