If you successfully "deflect" an attack, and change its path, then it deflects you right back. For human-scale melee weapons, the miss is what matters, and the side effects are assumed to be small enough to be negligible. For extreme cases, the side effects themselves matter, even when that's far less energy or momentum change than the total possessed by the incoming weapon.

The existing DB rule doesn't account for that, as it has zero momentum transfer on anything but the most marginal success. (It's also not especially accurate, since DB is related to the size of the shield, not its angle or how well it was employed, but that's not particularly worrisome in this case.)
