Most black logos appear to have two different ink layers. One dark and one a lighter/shading layer. On these plates it would also include details for other parts of the card.
The NY logo would be on different ink plate layers then the single St L.
It's possible they didnt have the updated PB plate (remaining card details minus NY) and had to use one of the two original NY plate layers for the remaining details to fill out the card and then used the St L plate.
Maybe the coupon uses only the lighter/shade NY layer and the St L layer and that's what you are seeing.
