Helina is also having JVC.@hellbent made this poster:

The 2 missiles are mostly the same. There is a difference in thrust vectoring mechanism though. Dhruvastra's JVC should allow the IAF to do some very steep angle targeting, but that would come at the price of speed. IA's Helina should be a faster missile & better suited for plains.
I am not sure why they are doing this though. Maybe the plan is to deploy IA's attack helos around Rajasthan & Gujarat. While the IAF deploys their helos at higher altitudes up North. Remember IAF's Apaches & LCHs are being deployed in Ladhak.
Helina is also an AGM like Dhruvastra & SANT.
