How would the prop setting affect the zero thrust setting?

My aircraft's POH gives a zero thrust setting with the prop fully coarse (but not feathered), I think it's 8" off the top of my head. My employer prefers us to leave the prop fully fine (which seems sensible in case the student advances the wrong power lever on go-around, for example), with more like 12". Is there any reason (other than the one I've stated) why one setting should be preferred over the other?

As for JT's point, I've never considered that. I've always been taught - and taught my students - to close the throttle for both the live and the dead engine as they come into the flare, thus removing any asymmetry. But perhaps a more realistic asymmetric landing would involve leaving the throttle on the dead engine alone in the flare (or perhaps the instructor should reduce the power slightly to maintain a thrust setting which gives zero thrust at the lower speed of the flare)? Like Keygrip, I didn't notice any real asymmetry during the flare the one time I've done it for real - but it was my student who was handling the aircraft, not me.
