Major magic Phantom Thief Rogue and the Elf favored class bonus

[Woodoodoo]

An elf rogue with the favored class bonus for his class gets to take multiple major magic rogue talents. Does the favored class bonus increase his uses of all of his instances of major magic?

[UnArcaneElection]

The way I read it, each time you select it, it works for one instance of Minor Magic or Major Magic. Note that the Favored Class Bonus wording is broken for Unchained Rogue, because Unchained Minor Magic cannot benefit from this (it is already unlimited casting), but they didn't update the Favored Class Bonus wording for Unchained Rogue, so it still says you have to take it at least as many times for Minor Magic as you take it for Major Magic.
