There is another possibility here, as well, besides the new engine architecture. That is, it could be errant data. I.e. it could just be a plain old mistake.
True, the fact that the old stroke size is the new bore size adds some weight to that assumption

BTW, the torque output from changing bore/stroke combo's can be simulated. There are specialist engine simulation software available, which computes loads/vibrations/torque, etc. But rule of thumb is a longer stroke always gives more torque than same displacement short stroke engine.
