I disagree that it does.

Also in the link you've provided Seinfeld only says "You could never do that today". You've interpreted that as him conceding that the episode didn't age well. That's a stretch. (To be fair, the title of the article suggests he's admitting it's offensive but there doesn't seem to be anything to back that up).
