OK, here's a question for the SP folks.

I took a ride on #14 up the Coast Line many years ago. I noticed in many places we would pass an opposing direction ABS signal and it would display a yellow or flashing yellow behind us, despite no trains following behind. Why wouldn't it immediately display a clear if the blocks behind us were empty? This wasn't a momentary phenomenon, they remained in this state as far as I could see from the rear of the train (at least 1-2 mins in many cases).
