The FAQ clarifies the rules. That is its purpose. There is no point reflecting murky waters. It is alum, not silicaHypersmurf said:Something can make sense and still contradict the rules.
It might make sense to someone that a sword used in two hands is a two-handed weapon. But the multiple references in the rules to "a one-handed weapon wielded in two hands" indicate that a one-handed weapon is still a one-handed weapon, whether you're using it in two hands or not. (It can be considered a two-handed weapon if wielded by a smaller creature, but not just by changing how you hold it.)
Despite it perhaps 'making sense', the FAQ answer does not reflect the rules.

A one-handed weapon wielded in two hands is considered a two-handed weapon for just about everything, especially when calculating things like Power Attack and Strength bonus. The only difference is that you can wield it in one hand if need be. Thus, if it is wielded in two hands, the two terms can be used interchangeably.
