It seems to resume playback whether I answer yes or no.
If you were in the middle of a song, you will continue from the middle of the song if you select yes. If you select no, play will start a the beginning of the song.
The wording is a little confusing. I prefer the mask to state resume from beginning / resume from current position. If you select “no” in the later mask version, it resumes from the beginning, rather than the bookmarked position.
