W/kg in orange?

I’ve notice that sometimes, in the Nearby Riders tab, a riders w/kg is in Orange instead of white. Does anyone know why? I know about the little explanation mark when the data is dodgy, is this something similar?

Mine turns to orange or red when output rises above either 7 or 8 watts/kg (obviously during a sprint).

If they hold those w/kg for an extended time they will get flagged and receive a message to check their setup.
