As POSIX specifies.  Why do you think it should not be?

 From http://www.opengroup.org/onlinepubs/009695399/utilities/getopts.html
When the option requires an option-argument, the getopts utility shall place it in the shell variable OPTARG . If *no option was found*, or if the option that was found does not have an option-argument, OPTARG shall be *unset*.

I believe that the operative paragraph is the one that begins
"When the end of options is encountered".  It does not specify
that OPTARG be unset.  I will take a look, though.
