Hi there, the same thing happened to us. We applied for a Supervisa for my mother-in-law - we bought 1 year medical insurance also. However she got a V-1 visa, which is the visitor's visa. But her passport will expire Sept 2015 and her permanent application file is in Delhi - it is next in queue for processing. We think that is why she did not get the Supervisa and it is her first time travelling out of the country.
Thanks!
