In your 3rd query the OVER clause is being ignored because there is no 
associated Aggregation Function.
This has been fixed in HIVE-4214. The query fails with the following error:
'cannot recognize input near 'range' 'OVER' '(' in select expression'

The Windowing behavior in Hive is documented in HIVE-4197
