On Vertical Mills, the 4th Axis is frequently parallel to X or Y, and is laid down. On a Horizontal Mill, the 4th Axis is also parallel to X or Y, but it is standing up. Both methods work great, but the horizontal mill's standing 4th axis frequently has more clearance available since the work is never trapped between the table and the axis.
