Passive Disable Conflict?

[GodOfAtheism]

I'm a bit confused with characters that have a passive that states they are immune to passive disable. In the same passive description it also states that the passive can only be countered by passive disable applied at the start of battle. If they are immune to passive disable how can passive disable render it useless? Is the description faulty or am I missing something here? As an example Senjutsu Eddie has that description in his passive Bushido Code Honor. Can anyone help me understand this?

If you take a character such as The Prisoner (whose Passive carries a Passive Disable) into battle against them, then the passive is disabled. It's the only time it can be disabled: before the battle starts.

To add to the above example, it means that characters like Dark Lilith, who apply Passive Disable with their basic, won't add that effect. One thing I haven't tested is whether going first or not makes any difference with the Prisoner passive; i.e. I don't know if the Prisoner's Passive is still applied first if the team he is on goes second...
