What you describe is a DisplayPort MST setup, also referred to as daisy chaining. macOS does not support DisplayPort MST setups with multiple displays. That is why both displays in the chain are mirrored. To put that another way, the behavior you are seeing is the result of an operating system limitation.

Oh Ok thanks for letting me know. Guess that will not be fixed from Apple.
