I don't have previous (TM2) speaking engines, so I think someone who has them could better explain to us the system of operation of this light / sensor. I guess with it, the engines recognize and talk to each other. As far as I’ve seen watching videos of talking TM2 engines, the sensors recognize each other, talk to each other, and the lights go out and on depending on their conversation and their movement.
And that these engines really "talk" to each other, just like the earlier ones, is almost certain. Because, why else would they advertise these trains with pictures like this, which directly depict “conversation”:
