It's for simplicity, I suppose

Why treat it as two though in the processing?

It allows the same algorithm to be applied to all channels, with no modifications. Then as the processing proceeds, it's not necessary for it to identify which channel it is working on. I'm not defending Nikon's choice, rather I'm just stating what they've done.

Make more sense to treat

[G1] [? ][G1]
[? ] [G2][? ]
[G1] [? ][G1]

as just:

[G][? ][G]
[? ][G][? ]
[G][? ][G]

I could actually try this. I will be running a simulation of the clipping algorithm fairly soon, as verification of my interpretation. When that's done, I can experiment with variations such as your suggestion, to see how they behave.
