Does Yahoo's PlaceFinder API always return 0 or 1 result for a reverse (lat/lng) lookup?

Question

I'm familiar with the geonames API, whose findNearbyPlaceName resource takes an optional radius parameter and can return multiple places for a given lat/lng pair.

When doing a similar lookup in YDN PlaceFinder, using the R gflag to do a reverse lookup from a lat/lng, will there ever be more than 1 result returned? I have not found any instances yet, and from what I can tell, the PlaceFinder API doesn't allow for radius (though you can request offset from street).
