That's an interesting observation. The original bridge would have been vertically laminated without cap, I presume. So a horizontally laminated cap was put on the vertically laminated base? (material routed off to make room). Kind of like the Steinway design, but the cap being laminated? That would appear to support the notion that RH related unison smear is connected to lateral movements within the bridge, ie swelling and shrinking in a width-wise direction, since vertically laminated is quite free to move in that dimension.
