I think they were just trying to be cute with omega being an ancient machine they use outdated terminology

It's not too hard to either just remember starboard = right side which may serve you in real life at some point
or
"l"arboard = left

i'd be more on board with people making this out to be super confusing if there were complaints about bright blade and dark blade or any of the other left and right moves that don't use actual terms for left and right at all
