argument precedence, output redirection

[Payam Poursaied]

Hi all,
I'm not sure this is a bug or please let me know the concept:
What is the difference between:
ls  -R /etc/ 2>&1 1>/dev/null
and
ls -R /etc/ 1>/dev/null 2>&1
 
the second one redirect everything to /dev/null but the first one, still
prints errors (run as a non root user would unveil the problem)
it the order of arguments important? If yes, what is the idea/concept behind
this behavior?

Best Regards
