Much thanks. This "heals" my suspectedness.

On the other hand, according Nicolas George there seems to be a possible incorrectness according packets count.

Anyway, in my case the packed count seems exact enough. I transcoded a MPEG2 file with 25 fps to Matroska and was wondering, that the output has 50 fps, so I wanted to verify, if the output really has ~ twice frames than the input.
