I think this is a misunderstandig, maybe caused due to translation.
Now, im my german editon of this book this statement refers only to
the 50-mm standart- (!)- lenses, which should set to infinity.
For ease of setting, and there is no gain with tins lenses.
Slide copying with the 3.5/50 Macro is discussed in the paragrah before, as a
better
possiblity. He advices to set the focusing barrel to 0.3m, to get the best gain
from the close
focusing mecanism. But the bellows must be aranged in a more complicated way.
