The problem is that these 4 bytes are not occurring within a 
"system_header".  Instead, they are occurring (exactly every 2048 bytes in 
the file) inside "slice" data.  (Note that the data is Video Elementary 
Stream data, so the relevant specification is 11172-2, not 11172-1.)

According to the MPEG specifications, I don't see how it is legal for video 
stream ids to appear arbitrarily inside Video Elementary Stream 
data.  (However, please correct me if I'm wrong.)
