I think this is all related to this slide from SDCC...

As you can see in the slide, the Naboo Pilot, Mawhonic, Aurra Sing, and Gungan were all part of Vintage Wave 4 at one point... obviously something changed since they are now apparently in ths Walmart Ep1 wave.
The JTA list doesn't really mean anything definitive - it could just be an error on Hasbro's part (maybe they simply grabbed an old list) or it could be interpreted as sign that those four will ship in both the Walmart exclusive wave (on the Ep1 cards) and again in the Vintage line (Vintage cards). Wait and see I guess...
As for why Ric and G8 aren't numbered in JTA's list - if that's a vintage number list and these are technically NOT part of the vintage line, but rather put on the new Ep1 movie cards as some folks were reporting at SDCC, then it would make sense they wouldn't be part of the vintage numbering...
