PVS-Studio warning V557 for IPP Samples

Ipp32f pa_nb_long[NUM_CHANNELS][2][MAX_PPT_LONG];

MP3Status mp3enc_psychoacousticInit(....)
{
  ...
  for (ch = 0; ch < NUM_CHANNELS; ch++)
    for (i = 0; i < MAX_PPT_LONG; i++) {
      for (j = 0; j < 3; j++)
        state->pa_nb_long[ch][j][i] = (Ipp32f)1.0e30;
    }
  ...
}

This is what should have been written here: for (j = 0; j < 2; j++)

This suspicious code was found in IPP Samples project by PVS-Studio static code analyzer.
Warning message is:
V557 Array overrun is possible. The value of 'j' index could reach 2. mp3_enc mp3enc_psychoacoustic_fp.c 361
