If it doesn't take correlations into account, then the total # of identifying bits (aka entropy) will simply be the sum of # of identifying bits in each category, which does not seem to be the case. Therefore, I will guess it does take correlations into account (presumably by calculating the total # from uniqueness of the fingerprint only).
