Actually no - you can find the errors just as well without adding the
wikidata tags to OSM as after doing so.
The perpetuation of errors is one of the primary reasons why mechanical
edits are often not considered favorably in OSM.

I don't really want to argue this here - as said i have no objections
against having wikipedia/wikidata tags as references for 'related
features' but many treat these references under the assumption that
they indicate identical real world concepts exist on both ends - or
even worth: they might think a lack of identity is an indication for a
factual error in the data on one side. I wanted to point out that this
is a fundamentally incorrect assumption.
Don't assume such cases are just a freak anomaly - they are not. OSM
and wikidata are two very different projects which developed in very
different contexts. Just another example: For most cities and larger
towns (at least in Germany) there exists an admin_level 6/8 unit with
the same name and most of these seem to have a single wikidata item
while in OSM we have two separate concepts for the populated place
(place=city/town) and the administrative unit (boundary relation with
boundary=administrative + admin_level=6/8).
