That back yoke detail appears to reflect no such motive, but is just there to say "This is a Taub!"
Well, I think there's a little bit of a designer in every tailor and in the early days the tailor was the designer.
The yoke is just a decorative feature. As to it saying "I am a Taub" doesn't a house style do the same thing? Rubinacci have a distinctive cut that announces "I am a Rubinacci" does it not?
Back treatments like this aren't new, take a look at some of the old pictures of sports coats from the 30's. You'll find a bewildering range of back treatments, some functional like a bi-swing others purely decorative
Here is a pattern Taub's created for a jacket with a curved yoke amongst over features.
Don't be put off by these types of tailors, there's a tendency to think that they can't cut a conservative business suit. Most of their business is likely to be such business suits.
In some ways though they are the very definition of bespoke tailoring, in that they are flexible and willing to collaborate with the customer to make something unique and special, like Rubinacci did with your coat.
