Perhaps some SRD quotes?
The key point here is that an enhancement bonus on armor does not enhance your Armor Class directly, it enhances the armor bonus of the armor you're wearing. Thus what the rogue in question has, essentially, is a suit of studded leather that provides a +5 armor bonus, as well as bracers that provide a +4 armor bonus. Since they don't stack, only the armor bonus from the leather will apply.
3.0 SRD said:Armor Bonus: The protective value of the armor. Bonuses from armor and a shield stack. This bonus is an armor bonus, so it does not stack with other effects that increase an armor bonus, such as the mage armor spell or bracers of armor.
3.0 SRD said:Enhancement: An enhancement bonus represents an increase in the strength or effectiveness of a character’s armor or weapon or a general bonus to an ability score.
