Also, so far I have never seen a WD1770 in a 1581, the ones > I have seen used the WD1772 or VL1772. I've seen the schematic, this is a good point, they correctly used phi2's high phase this time, it means using phi1's low phase wasn't such a wise choice after all :) Maybe they've left the same NOP macro just for laziness? I think the definitive answers can be had by just recompiling without the NOPs and check what happens (after making sure the schematics agree with the actual circuit).
