It is a technique intended for the usage of big screens where moving the cursor for a long distance is a pain for the user.

There are multiple cursors shown simultaneously. When the user moves the real mouse, all cursors will be moved at the same time.

As we can think of, there can be confliction where multiple targets were selected simultaneously.
To avoid that, they use a queue to block all INACTIVE cursors. Only the first cursor reaches a target will be active. All other cursors will be blocked in which state they won't move until the ACTIVE cursor leave its target.
