it will generate different number of frames per passes ONLY if
- a-v sync engine parameters change (-mc / -noskip / -skipmax / -nobps)
- audio codec changes (for example -nosound or -oac copy at 1st pass, mp3 at
  second), maybe audio codec parameter changes are enough, but imho not
- encoded area changes (-ss/-end-at etc)

i suspect he changed audio codec between passes...
