Unfortunately it does not return the bounds of the matched feature. We use this to determine if results are accurate enough, by measuring the area of the bounds; for example, if the match is a long road (not a numbered street address), it makes no sense to use the latlng because it's quite obviously too imprecise; but if the road is quite short (less than 100m, say), it's acceptable to us. It's such an obvious feature to provide a geocoding API that I don't know why only Google does it.
