Isn't this now missing the previous comparison if nord > current_nord ? While the first two invocations hard-code current_node=0, the last two are run in a loop with current_nord between 0 and max(nord), which should - unless all nord values are the same - filter some edge computations, no?

Forgive my ignorance, but is there a way that this could be written as a loop as in copy_corners() rather than explicitly writing out every element?

There is. This re-write is due to ongoing performance engineering work on CPU - it's not necessarily going to stay that way in the long run.
It's also a studying case for us of a few things:
- a code that triggers heavy micro-op reject in stencils mode leading to poor performance
- a case of code that needs to "escape" the SDFG and remain in the full program optimizer purview
