What is the fleur de lis doing in Chaturaji?

I've started playing Chaturaji again after taking a short break from it and noticed these fleur de lis icons on the board. What do they mean? At the beginning of the game, they start on the king squares but they move around all over the place throughout the game. Someone told me it means it's a royal piece, but I can't imagine that would be very useful. 

I think it is just some cheap junk to distract you. Ignore or tell Chess.com

That's what I think, too. I submitted a bug report because, at the very least, it's completely broken. I think they should remove it altogether because everybody knows which piece the king is. I can understand for courier chess because there's another piece that looks the same, but for everything else, it's junk.

The king isn't always the royal peice...
