I followed your second example:
https://trac.ffmpeg.org/wiki/Encode/FFV1#Examples1
I tried with different sources, same result, so you should be able to reproduce it with one of your files.
Note:
See TracTickets
for help on using tickets.
2pass mode works fine if the range coder is selected.
With golomb it cannot work and produces 2 identical files.
I will add a check so this triggers an error
