As far as I can tell, this part is meant to extract the information from the data returned by:
But that’s all I can see. This:
…doesn’t interpret the extracted information at all. That might be done here:
…if this was successful:
so the only way this:
could override this:
…is if this was successful:
And that needs:
So, I honestly don’t think your problem, whatever it is, has to do with either xdg-open, nor the shell.

Tip
When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:
```
pasted text
```
Or three (3) tilde signs, like this:
~~~
pasted text
~~~
This will just cause it to be rendered like this:
Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.
Instead of like this:
Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.
Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.
Thereby increasing legibility thus making it easier for those trying to provide assistance.

Just had an epiphany on the toilet, thanks toiletfaeries!
This:
Extracts the info from this:
I think 
So if this:
isn’t successful, then this
won’t happen, causing this:
not to be overrode.
So it affirms my previous diagnoses, that whatever your problem is, I don’t think it has to do with either xdg-open, nor the shell.
I’ve known people who actually do confuse Austria with Australia… the same types of people who seem to think Europe is a country.
