No it's not. The description presented when you highlight the option states:
"Enables sending AC3 directly to your sound card's SPDIF output, ***on
sources which contain AC3 soundtracks*** (usually digital TV). Requires
that the audio output device be set to something suitable".
The asterisks were added for emphasis. As you correctly stated, this
analog stereo source doesn't and couldn't contain an AC3 soundtrack so
according to that definition this option should have no effect.
So either that blurb of text needs to be updated or the behavior of the
option needs to be changed. I think the latter one would be preferred.
