Does OpenFDA have duplicate reports?

Open Data Asked by Lediona on September 30, 2021

In an answer of this specific question on stack exchange:
What does some reports have the same safetyreportid?
It is stated that openfda has duplicates:
‘Duplicate and incomplete reports are in the system: There are many instances of duplicative reports and some reports do not contain all the necessary information’

However, checking openfda site for the duplicate field description:

Screenshot of Searching OpenFDA for "duplicate"

The site states that openFDA shows only the most recent version (meaning there is no duplicates on the openFDA)

I am a bit confused whether the openFDA API data provides duplicates or not.
I would love to hear more clarification about this matter.
