Yes, it is setting the DE variable (internal to xdg-open) to generic.
You can temporarily alter the environment of a command by prefixing it
with `var=value '.  The cool thing is the current shell does not retain
the temporary value.  Here is an example:

  $ var=foo
  $ var=bar sh -c 'echo $var'
  bar
  $ echo $var
  foo
