A speculation:
Could it be to prevent "self-masking"? I understand that cyanotype is kind
of self-masking process - because it prints out with considerable amount of
density - and maybe if one expose with just Ferric Ammonium Citrate there
will be less density before Potassium Ferricyanide developing which means
less self-masking?
