intraday vs overnight , 50-50 vs 100% margin ?

Zerodha says "

 

You will be able to use this entire margin after haircut for taking intraday or overnight positions in Futures, and for writing Options of equities, indices, and currencies. You will not be able to use this margin to buy Options or take further positions on the equity segment "

 

So Does it applicable to FYERS ?,  This 50-50 margin only for over night positions only ? and It won't be applicable to intraday/expiry day options ? 

Or  

FYERS go over and above the SEBI rules and ask 50-50 margin for intraday also ?
