The 'quick' is in relation to the cause, not the effect...if you are quick, then the autosaved info stays in the browser. You come back to it, the Editor detects it and populates etc.
This may or may not be relevant to your own situation - but the reason the Editor populates data and prompts is because the JS to clear the autosave didn't clear the autosave. That is what would need to be investigated, not the effect of it at a later point.
