That'd be sweet if it was true, but I'm pretty sure that the ring he gave her was a plain gold or silver band, no design on it.
The fact that WHATEVER you name that ring it is the same name in the future. So the time and place where squall names the ring is directly proportionate to influencing the name of the GF in the future.
Squall doesn't actually name it in that scene; he simply tells the name to Rinoa. The game lets the player decide on what the animal is called, basically. Just like when you name the characters at the start, you're not changing their name, just confirming a detail.
