Chocobo class barding

[Galactimus]

If:
Your Chocobo reaches Rank 10 in one tree, you can re-spec it and claim the barding of the second tree (Because you have not yet claimed the barding from the NPC)

False. When you reach Rank 10 in a single tree the barding is automatically added to your list of bardings. There is no NPC to talk to. If you put 10 ranks into Defender your chocobo automatically receives the Paladin barding. There's nothing you can do once you give your chocobo that 10th Rank.
