Some lines I can't understand #85

Hi, I have some confusion about the lines (127-133) in feature_extractor.py , I can't understand why 'good_grammar_ratio' should calculated like that. As I see it, good_grammar_ratio should be calculated as good_grammar_ratio = len(overlap_ngrams)/len(pos_ngrams), could you explain your calculation for me? 

if (len(pos_ngrams)-len(overlap_ngrams))>0:
      divisor=len(pos_ngrams)/len(pos_seq)
 else:
      ivisor=1
if divisor == 0:
      divisor=1
good_grammar_ratio = (len(pos_ngrams)-len(overlap_ngrams))/divisor
