I'm looking at the table that's just above your quote, and that should provide some more insight.
Of course my last airline you just told the other guy, "I'm gonna fly a little fast" and he knew you were correcting for the gusts. At my current airline there's no provision for that sort of thing.
I don't know why we don't just add Gust to the REF and get a "REFgust" and then add the wind on top of that for approach speed (eg REF30 = 133. REFgust = 140. REFgust+5 = 145 for command speed for wind 10 gust 20)
