'what's difference between `2>&1 >/dev/null &` and `>/dev/null 2>&1 &`

Had found 'What's difference between "2>1 > /dev/null" and "2>&1 >/dev/null"? ' and '1>/dev/null and >/dev/null and &>/dev/null', but they can't make me clear the problem about my question.

  • 2>&1 >/dev/null &
## Ubuntu 16.04
root@lm-pc:~# nohup python -m SimpleHTTPServer 8088 2>&1 >/dev/null &
[1] 31509
root@lm-pc:~# nohup: ignoring input and redirecting stderr to stdout
^C(cursor stuck in here)

## Debian 9.5
root@ops:~# nohup python -m SimpleHTTPServer 8088 2>&1 >/dev/null &
[1] 5503
nohup: ignoring input and redirecting stderr to stdout
root@ops:~# 
## auto finish and cursor flash in the head of new command line
  • >/dev/null 2>&1 &
# nohup python -m SimpleHTTPServer 8089 >/dev/null 2>&1 &
[1] 31546
#
## Ubuntu 16.04 and Debian 9.5 are the same result

What's the difference between these two format?
