Is Bracket orders independent of each other?

Is bracket order in Zerodha independent of each other?

Say I have one single srip TATASTEEL

1 BO - BUY 500 Target 520 SL 498

2 BO - Sell 500 Target 450 SL 502

Will these orders cancel each other or operate independently. I am using another broker where such orders are getting squared-off against one another.
