What is that last set of icons in spectate.bm2 used for?

[Fenix]

The spectate.bm2 file holds graphics used in the player list stat box and most of it is pretty obvious in what it's used for... Tick mark, spectating player, attached player, and ticked variants of the previous two.

But there's also a graphic in there that is of a yellow square and all combinations of the tick/spectate/attach with it. Does anyone know what that yellow square is supposed to signify? I don't recall ever seeing it on the player list.

Being it is yellow, it is related to your team

King of the hill?

I feel like I recall it, but been so many years. Gonna have to play around now.
