In which region does a multi-region Lambda function log?

If a Lambda function has the permission to log its activity in different regions, how does it "choose" where to log?

Does it log in its own region, unless explicitly instructed to do differently?

I need to know, because I have distributed the same function in 3 different regions for performance purposes and, for the sake of simplicity, I have associated the 3 instances of the function to the same role, so they are allowed to log in 3 regions.

So far, I have noticed that they actually log always in their own region, but I would like a confirmation.
