This looks like regular faceting to me.

1. Showing citycounts given state
facet=on&fq=State:Karnataka&facet.field=city

2. showing statecounts given country (similar to 1)
facet=on&fq=Country:India&facet.field=state

3. showing city and state counts given country:
facet=on&fq=Country:India&facet.field=state&facet.field=city

4. showing city counts given state + all other states not filtered by
current state (
http://wiki.apache.org/solr/SimpleFacetParameters#Tagging_and_excluding_Filters
)
facet=on&fq={!tag=State}state:Karnataka&facet.field={!ex=State}state&facet.field=city

5. showing state + city counts given country + all other countries not
filtered by current country
(s<http://wiki.apache.org/solr/SimpleFacetParameters#Tagging_and_excluding_Filters>imilar
to 4)
facet=on&fq={!tag=country}country:India&facet.field={!ex=country}country&facet.field=city&facet.field=state

etc.

This has nothing to do with "Hierarchical faceting" as described in SOLR-792
btw, although I understand the possible confusion as County > state > city
can obvisouly be seen as some sort of hierarchy.  The first part of your
question seemed to be more about Hierarchial faceting as per SOLR-792, but I
couldn't quite distill a question from that part.

Also, just a suggestion, consider using id's instead of names for filtering;
you will get burned sooner or later otherwise.

HTH,
