The Irrelevant Oncoming Traffic Light

Hello. My apologies for not writing yesterday. It was an Ontario holiday.
There is a road in my town where the 4 lanes are together, separated only by the double yellow line. As you're going southbound, the road becomes separated by a concrete median. For some reason, at this point there is a flashing light indicating there is oncoming traffic in the other lanes coming towards you.
I consider this light to be irrelevant. Why? Because there was oncoming traffic long before this point. And there was no median to protect us. Why then have this light right where we are separated from the oncoming traffic by a median? Why not have it before this point? Why have the light at all?
Have people driven into the oncoming traffic? No, with or without the irrelevant light.

Regards,
Irrelevant
