I remember someone at M commenting on the care that they took in making sure that the HDMI pins signal runs on the PCB of the HDMAX 421 (121?) were identical - looking at the runs on this PCB, possibly they need not to have bothered ?

Or maybe all the symmetrical stuff is layered within the board?
