Some hard bosses can invoke a "Leader Skill Lock" effect on your units, which effectively disables your squads leader skills' effect on the affected units. So if your leader skill was to negate all status ailments (and you had no other form of negation like spheres, extra skills, etc.), then the units affected by the leader skill lock will no longer be protected from status ailments. Estia's LS disable purge basically just removes the leader skill lock effect from your unit(s) so they will be able to benefit from your leader skills again. I think this purge is fairly unique, which makes Estia a good unit to have (along with her other benefits such as cleansing DoT). Let me know if I can help clarify anything else! :)
