As far as I understand, it is the same idea behind it as for custodes and 
mensural flags: for notes that are on stafflines, you have a different 
stem/flare length than for notes between stafflines.

See, e.g. in custos.cc:

...
  if (adjust)
    font_char += (((pos ^ sz) & 0x1) == 0) ? "1" : "0";
...

or in stem.cc:

...
    /* Mensural notation: For notes on staff lines, use different
       flags than for notes between staff lines.  The idea is that
       flags are always vertically aligned with the staff lines,
       regardless if the note head is on a staff line or between two
       staff lines.  In other words, the inner end of a flag always
       touches a staff line.
    */
...

I am only wondering why this adjustment for 8th note stems is applied for 
downward stems only, but not for upward stems.  I guess, it should be 
applied to both.
