It may be that http://temperature.xyz/podunk and http://temperature.org/squeedunk return the same numerical value because the temperature in Podunk happens right now to be the same as the temperature on Squeedunk, but they are still two different resources.  What is more, http://translation.xyz/fr-en/bavarder and http://translation.xyz/en-fr/cat may *always* return the same string "chat", but they are nevertheless two different resources.

Yeah, fair point.  I wasn’t being precise enough in what I meant by “sameness” given what I was trying to explain.  Had you asked me about subject identity or we’d been having a similar conversation, then I assure you, I’d have had a better, more globally correct answer.

In this case, I think byte equivalence is enough “sameness” for the argument to carry, however. :)
