Correct, assuming you want to neutralize that image.
That's right, I fully agree with Andrew. White Balancing will not specifically correct for the main illuminant's color temperature, but it will also correct for ambient reflection.
And even after that, I often season to taste by moving tint/temp a bit.
I agree, one also doesn't white balance a Sunset ..., but seasons based on a WB neutral starting point. Suppose one is shooting under a green leaf canopy, the true illuminant's color temperature will be filtered green. Color balancing (most of) that green cast out, seems like a good idea, but leaving 'some' in might add to realism.
Cheers,
