Intraday Short Selling Position Square off for the same stock which i hold

Would like to have clarity on below trade-

If i am having 10 Nos stock of some x company in my holdings. For the same company if i do intraday Short Selling again for 10 Nos of stock. By end of the trading day i i haven’t bought the stock back, will my position get square off with the stock in my holding or there going to be fresh auto buying take place in my account.

If you don’t square-off your intraday position by cut-off time. The same will be squared-off by RMS, however if there is high volatility or low liquidity, then RMS too might not be able to square-off. In that case, the shares you hold will be debited from your holdings for delivery.
