No, they were not planning that. This is only about 3rd level domain as the paragraph you quoted says. Every other TLD don't sell those (afaik). Normally "someone.name" would be a domain, and they would own all the subdomains. .name allowed you to register "one.someone.name" and "two.someone.name" as completely separated domains with completely separated owners. I understand why they should grandfather in existing domains but this was just madness.
Ah, fair enough. I kind of thought that third level domain registration was the whole point of the .name TLD, so I was interpreting it as shutting it down.
So the weird part then comes in: are all second level domains that have third level registrations now reserved? Do they stop being reserved if the last third level registration expires without being renewed?
