Oops, sorry, it's my mistake.
They are from HMGenS (HTS-1.1.2).
In hts_engine, the following part corresponds to the above statements:

               /* copy pdfs */
               if (voiced[mcepframe]) {
                  lf0pst->sm.mseq[lf0frame][k+1] = m->lf0mean[state][k+1];
                  if (nobound || k==0)
                     lf0pst->sm.ivseq[lf0frame][k+1] = finv(m->lf0variance[state][k+1]);
                  else   /* the variances for dynamic feature are set to inf on v/uv boundary */
                     lf0pst->sm.ivseq[lf0frame][k+1] = 0.0;
               }

The above statements are included in mlpg.c.

For some reasons we did not include hts_engine in the HTS-2.0RC1.
In the next or final release hts_engine will be included.
