Does this news mean NON-PIO US CITIZENS can trade in India?

Reference to this news, does this mean a NON-PIO US CITIZENS can directly open a trading account with any broker in India and start Trading Derivatives?

Is there any other clearance still required, or other red-tapes involved?

I think this is applicable fr dollar denominated trading at Gift city & i believe with this oversees traders can opt for NSE directly instead of SGX. I might be wrong on this too!
