Indeed it did.

If I look at my town, there are several roads which are
officially-designated tertiary routes
for through traffic which have houses all along them.  Because they are
tertiary routes it is sensible to mark them as such and not as residential
roads.  Other
roads in town with houses along them are not officially-designated tertiary
Sometimes, such as road re-surfacing or the annual fair, an
officially-designated tertiary
route may be closed off and traffic diverted through the residential
roads.  But those
diversions are longer routes and involve three extra right-angle (or nearly
so) turns.

Did you look at the comment he/she left about the reason for the change?
That person
interpreted "unclassified" in its common sense and not in the UK road
sense.  To that person, "residential" is a classification and therefore
cannot be
unclassified.  In OSM "unclassified" means a quaternary route which many of
interpret as not being a residential road.
