I imagine there was a lot about the times that we aren’t privy to when we make our judgements. We’re not playing with a full deck of cards, if you will… ;)
It's like, did you ever play a competitive video game with your friends as a kid? Smash bros or starcraft or whatever? And then when you grow up you find out that even the best of you is completely horrible compared to even a low ranked real competitor. It's almost like a totally different game.
Back then so many more things were like that.
Why they went for a scallop cut, I have no idea, but from my text it seems like they were aiming to break the salmon cuts down into grades.
And actually, I guess we should remember that these are 'table carvings'. The fish has already been cooked more or less whole, and the cards are telling you how to carve and serve at the table. So at that point I guess, the scallop cuts are just.. pure show.

I imagine that deboning that thing after is a right pain.
