Yes, but it's my understanding that when on internal battery power the final power amp is bypassed/powered down, saving battery life. If you just dial down the final output it still uses the PA.

I serious doubt it bypasses final output because final stage would not have a gain of only 7db or so. It likely limits output by changing bias voltage in final section or driver to limit output and current draw.
