It must have been added as a design feature - someone thought it would look nice. It is relatively discreet, it just struck me as something you don't see very often from EG.
That seam on the medial (inner) side (less visible) is not really a design feature, but a way to save leather. A whole-cut (that's what the 'Piccadilly' really is) is extremely wasteful as far as leather is concerned. A whole lot will end up on the clicking room floor. If you divide the whole-cut into a 3/4 and 1/4 cut, you can lay the pattern pieces much closer together; think of (sexual) positions like 'tea-spoons' or '69'. As a result of this manipulation, you have less waste.
Oops, I hope I haven't disillusioned one or the other. But take heart, this way of penny-pinching was much more prevalent in the olden days, although it is still going on sometimes.
