That actually  is what he was talking about. Note the reference in his
question to setting on "auto" in RAW mode. Auto is of course a white balance
setting on a digital camera. He clarified in a later message as follows:

You're misunderstanding, but that's, um, understandable!

We're not talking about the effect of WB on the RAW data at the capture
stage; we all can agree that's just metadata and does not impact the
sensor data at all during capture.

We're talking about converting RAW files to B&W images; in this
process, your white balance settings - whether keeping the settings
your camera chose, or using custom settings after the fact - do affect
the resulting B&W file. Just as applying a curve to RGB color data
before converting to B&W would affect the B&W.

Best,

Roger
