Possible bug in TermInfosReader/Writer

Hi,

I don't understand this code:

if (ti.docFreq >= skipInterval)
  output.writeVInt(ti.skipOffset);

What does the skipInterval have to do with the document frequency? 
Shouldn't that be something like if (i % skipInterval == 0), so that the 
skip information is written regularly?

Opinions?

Regards
 Daniel

This skipping is probably for the first skipping within the docs of a term. 
The later skip info is written here in SegmentMerger line 337,
method appendPostings():

        if ((df % skipInterval) == 0) {
          bufferSkip(lastDoc);
        }
