That's correct - all non-command abilities automatically transfer from mastered jobs to your Bare character, like 2-Handed. So, if you're like me and have all the characters master all the jobs, by the end of the game, you just use them as a Bare character, who is very powerful - strength of a knight, speed of a theif, MP of a black mage, HP of a Monk, etc, etc.

Definately worth it.
