The method doesn't matter here because the programid is not blank.
Programid's are used if present, else it checks subtitle and/or

Notice near the bottom of this screenshot "Program ID: EP1922". Unless
there have never been as many as 2000 different TV program episodes
in the history of your country, this is not enough digits to uniquely
identify a specific show. This programid is not from zap2it which would
have "EP" six characters for the series and four digits for an episode.
If there was any show from any series with "EP1922" in oldrecorded, it
may match as a dup. However, based on your saying that all episodes are
marked as previously recorded, my guess would be that likely all episodes
of "Floor Filler" are also marked "EP1922" or something like that.
"Original Airdate" is a year rather than a date so that's wrong and
"Type: (1922)" is obviously wrong.

These aren't checked because there are programids.
