My allies' ally's sensors are... my sensors...?

Hi!

I'm contemplating making an alliance in a game I'm in currently, but had a quick question. Myself and a current ally have mutual sensor-sharing. If I make a mutual sensor-sharing alliance with another empire, will that empire have access to the sensor information of my first ally?

So, to clarify: I am Empire A. I am allied with Empire B, and we share sensor data. If I then ally with Empire C, and share sensor data with them as well, will Empire B have access to Empire C's sensor data, and vice versa?

I'm running version 1.35 with the Balance Mod 1.07.

Thanks!
