It seems like you are assuming quite a bit about 2.
I think what GP was getting at is that is something along the lines of if you were accused of misconduct, and in being called into your manager's office for them to ask you about it you behaved unprofessionally enough they no longer thought you were a good fit for the company regardless of whether the accusation was true, they are entirely justified in wanting to end employment. A falsehood can reveal a separate truth about someone.
E.g. Someone falsely says you are always late to group meetings for a group project, and in being questioned you start throwing out racial slurs. Whether you were late is now a lesser issue, and while you woulf be technically correct to say you were falsely accused of being late to a few meeting and were then fired, that isn't correctly relaying the relevant information about why you were fired.
I have no information about whether this is what happened, but I think this is what the GP was trying to express about the information we have as it was presented.
