I don't know if it's the full explanation...

The way it should work is ppsrc should disable everything else , given if
input src ,and ppsrc have the exact same timecodes

In theory, you should get same as -vf decimate on preprocessed.mkv

ffmpeg -i preprocessed.mkv -vf decimate -c:v libx264 -crf 18 -an

gives drops at - 1019,1024,1029...

The interval is different and there are 2 more frames , 138 vs. 136
