so reading from this table -
https://chromium.googlesource.com/chromiumos/docs/+/master/constants/syscalls.md
why is the system call to write to the terminal = 4 on a 32 bit architecture and the system call number on it's 64 bit cousin = 1

The 32 and 64 bit tables seem to have many differences. Obviously the "port to 64" has not been a simple "copy-paste", but a real redesign.
