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
officially-designated
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
routes.
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
system/OSM
sense.  To that person, "residential" is a classification and therefore
cannot be
unclassified.  In OSM "unclassified" means a quaternary route which many of
us
interpret as not being a residential road.
