Those are not quite the same though, being something specific and short so essentially behave like a tld in their own right. For a long time you couldn't buy a <something>.uk, it had to be .co.uk or similar, so those _were_ the tld.
The way .name worked you could directly register <name1>.<name2>.name instead if getting <name2>.name and setting up <name1> as a subdomain. It meant john.smith.name and dave.smith.name could be completely separate registrations. You can't generally register <name1>.<name2>.tld like that.
