They're not fact-checking the source as though the source is trying to offer it up as legitimate. They rightly affirm the Babylon Bee as a satire site, so the only person they're actually fact-checking would be a person offering this story up as actual fact, which the source doesn't do, because it's a satire site.
And sure, that would apply to the Onion as well.
The are still fact checking Babylon Bee's claim, which I think it would be fair to say they are fact checking Babylon. It's semantics, but your "correction" applied to superman's post comes off as way too picky imo.
With that being said, It says more about the people who asked snopes to verify the validity of this "claim," than it says about snopes itself. It would take an additional 5 seconds to see that Babylon Bee is satire website. Instead, I am sure snopes received numerous requests to verify the claim.
