Why does cursor order change when rearranging displays on Mac Studio?

My Mac Studio M1 with Sequoia 18.5.1 desktop setup includes three displays named y(1), y(2) and y(3). For the cursor to move correctly from left to right when changing from one display to another the displays have to be arranged as y(3), y(2) and y(1). If I arrange them like I want, y(1), y(2) and y(3), the cursor no longer follows the normal left to right order. This certainly not urgent, but it is annoying. TIA.
