Acorn designed the board for a transition connector, not a PCB header,
and they are often that way round.  It's designed to fit the cable
without any extra twist, allowing it to be shorter.  If the header was
a straight one instead of a right-angle one it would be perfectly
capable of being fitted the right way round; that connector is not
original (I wonder who changed it and why?)
