[FFmpeg-user] Why are these different?

[Mark Filipak]

Command 1:
  ffmpeg -ss 10 -copyts -i this.m2ts -map 0 -c copy -sn -dn -muxdelay 0 that.m2ts
Command 2:
  ffmpeg -copyts -i this.m2ts -map 0 -ss 10 -c copy -sn -dn -muxdelay 0 that.m2ts

Let's ignore all the errors both make. And let's ignore the individual errors that they make 
individually.

Should Command 1 and Command 2 make the same outputs? "Yes" or "No"?

I'm not trying to be rude. I'm simply trying to get a definitive answer to a question that goes to 
the heart of what ffmpeg is and does.

Mark.
