Blu,

I think that's just a poorly worded statement. To my knowledge there isn't a single JA in the game that acts that way, the closest ones are Devotion / Martyr, Accomplice / Collaborator and Sekkanoki. Those all perform a specific effect on the target, the ones above would create a buff icon until you used them up like ES / DA / CA / BA / Efflux / SA / TA and all the other JA buffs in the game.
