Actually, this line is correct. At least, for sh(1).
------------------------------------------------------------------------------
Simple Commands
If a simple command has been recognized, the shell performs the following
actions:
1. Leading words of the form ``name=value'' are stripped off and
assigned to the environment of the simple command. Redirection
operators and their arguments (as described below) are stripped off
and saved for processing.
-- (c) man 1 sh --------------------------------------------------------------
An example:
nx6125% /bin/sh
$ echo $VAR
$ VAR='tuesday' /bin/sh -c 'echo $VAR'
tuesday
$ echo $VAR
$

I´d like to inform you that the command-line in question is correct and works. It´s a little confusing when I first read it, and especially for beginners. But still, it works. So it´s no longer an issue. PR can be closed.
